A good COMSAE score for COMLEX Level 1 is 450 or higher, with 500 or higher as the ideal target. The NBOME's 2025 poster on COMSAE Phase 1 usage after the change of COMLEX Level 1 score reporting put a COMSAE above 400 at a 94% chance of passing, and the 2021 NBOME poster found that a COMSAE above 450 corresponds to a 99% or higher pass rate. That's the headline data, and the headline misses the messy reality: every cycle, we see DO students pass the real exam with sub-400 COMSAEs and fail with COMSAEs above 400. The score is one input among several, and the full readiness call (trend, qbank percentile, anxiety history, confidence read, school deadline) is what our free Postpone Calculator walks you through.

Plenty of students never hit 500 in the time they have to prepare, and that's genuinely fine. The real exam is pass or fail. Above 450 is the line we use to call most students safe to test, but only when the rest of the picture lines up. Below 400, the NBOME data says you've got under a 94% chance of passing, and that gap matters when a fail means another full dedicated cycle, a delayed graduation, or a residency cycle on the line. Trend matters at least as much as the absolute number. A 410 followed by a 460 reads very differently from a 470 followed by a 410, and we will green-light the first student over the second every time. Direction is half the signal.

What does each COMSAE score range actually mean for COMLEX Level 1?

The simplest way to read your COMSAE is to map it to a pass probability using the NBOME's 2025 poster and the 2021 NBOME poster. Below is the working translation we use with our 1-on-1 students, with the loud caveat that the NBOME data is a population-level average and you are a sample of one. We have green-lit students with sub-400 COMSAEs who passed comfortably, and we have postponed students sitting above 450 because the rest of the picture screamed not-ready.

  • Below 350: under 75% chance of passing per the NBOME 2021 poster. This is a postponement-conversation range, not a green-light range. Many students with sub-350 scores eventually pass the real exam, but walking in here without a plan to move the score is high-risk.
  • 350 to 400: roughly 75 to 94% chance of passing depending on which poster's range you sit in. Workable for some students, dangerous for others. We have seen plenty of students pass with a final COMSAE under 400, and we have seen plenty fail. Trend, anxiety history, and qbank percentile all matter more than the raw number in this band.
  • 400 to 450: 94% or higher chance of passing per the 2025 poster. Comfortable for most first-time test takers without a history of testing anxiety. Not the ideal, but a reasonable landing zone if your trend is up and your qbank percentile is solid.
  • 450 to 500: 99% or higher chance of passing per the 2021 poster. The standard "you are ready" range. If your last two scores sit in here, you are cleared to test under almost any reasonable circumstance.
  • 500 and above: comfortable above the COMLEX mean (which sits around 500). Ideal. Almost no realistic path to failure here unless something goes seriously wrong on test day.

A 470 and a 485 on your final two COMSAEs is a perfectly safe set of data points to walk into test day on. So is a 460 followed by a 480 with a clean upward trend. The framing is not "did I hit a magic number." It is "do my last two scores, taken close to test day, both clear the threshold I am comfortable with, with the trajectory still pointing up."

Why is 450 the standard COMSAE target for COMLEX Level 1?

The NBOME published two posters, in 2021 and again in 2025, validating the relationship between COMSAE scores and COMLEX Level 1 pass probability. Both pointed to the same line. A COMSAE above 450 corresponds to a 99% or higher chance of passing the real exam. That's the cleanest population-level data we have on a question students obsess over for the entire dedicated period, and population-level is the qualifier that matters. Individual outcomes vary widely, which is why we never call readiness on a COMSAE alone.

The 450 line is also useful because it sits comfortably above the COMLEX passing score of 400, with a real cushion built in. A student scoring 450 on a COMSAE has roughly a 50-point buffer above failure. That cushion absorbs a bad block, an anxiety spike, a question form that runs harder than expected, and most of the day-of-exam variance. Walking in with a 410 final COMSAE is technically passing range on paper, but it leaves no room for the things that actually go wrong on test day.

A second reason 450 sticks is school policy. Plenty of DO programs require a 450 COMSAE before the school will let you sit for COMLEX. Some require a 500. A handful set the bar at 425 or impose progress check-ins at 400 and 450. If your school has one of these gates, the right number to aim for is your school's gate plus a 20 to 30 point buffer, not the NBOME's 450 line. Hitting the gate exactly tends to mean retesting under stress when one bad block drops you back below it the following week.

That said, 450 is a useful target, not a verdict. We have walked students into test day at 410 with a clear upward trend, a clean qbank percentile, and a calm anxiety profile, and they passed without incident. We have also postponed students sitting at 470 because the rest of the picture (a 50-plus point drop on a recent shelf, a sleep schedule in the gutter, a trend that had stalled for 4 weeks) said not-yet. The COMSAE number is the loudest data point on the table, and it is rarely the deciding one.

How variable are COMSAE scores from form to form?

COMSAEs are not perfectly calibrated to each other or to the real COMLEX. Score variability between forms is real, and students often see swings of 20 to 40 points across two COMSAEs taken a week apart with similar preparation. The NBOME prefaces every COMSAE with a note that the form is not meant to predict your readiness, which is partly a legal hedge and partly an honest admission that scaled scoring across forms is not perfect.

What this means in practice: do not anchor on a single COMSAE. Anchor on two recent ones. A student with a 430 on form 110 and a 475 on form 111 is not a 430 student. They are something close to the average of those two, and the trend points to the higher number being more representative. The two-data-point rule exists because variance from form to form gets smoothed out when you average, and a single form is just too noisy to bet your test day on.

The other practical implication is that a 480 COMSAE does not mean you will score a 480 on COMLEX. The two scores are correlated, not identical. We have seen students score 50 to 100 points above their COMSAE on the real exam, and we have seen students score 50 to 100 points below it. The 50-plus-point drop pattern is the testing-anxiety signal worth flagging, especially if it is repeated across multiple standardized exams (MCAT, shelves, prior COMLEX attempts). That pattern is a separate diagnosis with structured treatment, and it does not get fixed by adding more Anki cards.

What if my COMSAE score is below 450?

A sub-450 score is not a verdict. It is a data point, and what you do with the data matters more than the number itself. Here is the honest read on what to do at each band.

If you are scoring 425 to 450 with 4 to 6 weeks of dedicated still ahead of you and a clear upward trend, you are on track. Stay on plan, push your weak topics with focused blocks (4 to 6 blocks of 44 questions per discipline, 3 to 6 per system), take one practice test every 2 weeks, and trust the trajectory. Most students in this range close the gap to 450 with a few more weeks of consistent work.

Students sitting in the 400 to 425 band with a flat trend over 4 to 6 weeks usually have a broken study system rather than insufficient effort. Common patterns we see: tutor-mode questions only (timing never gets practiced), passive content review without active recall, Anki used as a content-review crutch instead of a memory tool, and unaddressed testing anxiety masking real content knowledge. The fix is rarely "more hours." It is usually "different hours, with feedback."

Below 400 with a flat or declining trend, the postponement conversation is real. Two to four weeks of additional dedicated, with a different approach, is usually the right move. Longer than that and burnout starts to outweigh the extra prep time. Our free Postpone Calculator walks you through the standard inputs (recent two scores, qbank trend, anxiety self-assessment, rotation or LOA constraints, confidence read) and gives you a structured read on whether to push the date.

Previous test takers who dropped 50-plus points from their final COMSAE to their COMLEX score on a prior attempt have a different problem. The diagnosis is testing anxiety, not content. The buffer rule we use with anxiety-pattern students is to add the gap to the target. A first attempt of COMSAE 430 to COMLEX 380 means a retake target of COMSAE 480 or higher to land at 430 on the real exam. That gap closes with structured exposure work (timed proctored mock exams, away from home, in unfamiliar environments) plus, when appropriate, mental health support from a therapist or psychiatrist. Adding more Anki cards or another video resource will not fix it.

How many COMSAEs should I take, and in what order?

Plan one full-length practice test every 1 to 2 weeks during dedicated, with two tests in the final 2 weeks. The goal in those final 2 weeks is two consistent data points above 450. Above 500 is the ideal, but plenty of students never hit 500, and 460 to 480 in the last two weeks is a safe enough set of numbers to walk in on.

The COMSAE pool is limited, so the cadence matters. Three purchasable Level 1 COMSAE forms exist (107, 110, 111). Four school-administered forms are available at programs that release them (113, 114, 115, 116). The retail TrueLearn self-assessment and two COMQUEST self-assessments fill out the supply.

For a typical 6 to 8 week dedicated period, the order most of our students follow is:

  1. Start with whatever you have available. If you have plenty of unused COMSAEs, use a previously taken COMSAE as the baseline. Tight on COMSAEs, start with the TrueLearn self-assessment 6 to 8 weeks out and save your unused COMSAEs for later.
  2. Slot in a COMQUEST self-assessment 4 to 6 weeks out if you need to supplement. Repeats are fine for early data points.
  3. Continue with one practice test every 2 weeks, prioritizing COMSAEs whenever possible.
  4. Save 2 unused COMSAEs for the final 2 weeks. These are your last and most important data points before test day.

The TrueLearn self-assessment is worth a short note. Ignore the three-digit score and the "percent chance of passing" the platform spits out. Neither closely tracks real COMLEX outcomes. The TrueLearn percentile is the only output worth anchoring on, and even that is best read as one input among several. Above the 40th percentile in your last 100 mixed timed questions on TrueLearn is a healthy floor, with above 50th to 60th being where most green-light students sit going into test day.

How do I know I am ready to take COMLEX Level 1?

Readiness is not a single number. It is a small checklist of consistent signals that all point the same direction. The four signals that matter most:

  1. Two recent COMSAE scores above 450, taken within the final 2 weeks of dedicated. Above 500 is the ideal, but a clean 460 and 480 is a safe set of data points to walk in on.
  2. Question-bank percentile at or above 5 to 9% on the bank you have used most recently. That is the floor for passing test day. Above 40th percentile is in great shape.
  3. A clear upward trend in COMSAE and qbank scores over the last 4 to 6 weeks. A flat or downward trend is a postponement signal regardless of the absolute number.
  4. Honest self-assessment of confidence. The question to sit with is: "do I feel more confident now than when I started studying?" If the answer is no, the problem is rarely fixed by adding 1 more week of the same plan.

A solid readiness summary looks like this: "I scored 470 and 485 on my last two COMSAEs, my TrueLearn percentile has moved from 20th to 55th over 8 weeks, I am sleeping reasonably well, and I feel more comfortable on the bank than I did a month ago." That student is ready. A summary that reads "I scored 405 once and 395 once with no clear trend, my TrueLearn is at the 25th percentile, I am sleeping 4 hours, and I feel less confident than I did a month ago" is a postponement conversation, not a test-day conversation.

Frequently asked questions about good COMSAE scores

Is a 450 COMSAE good enough to pass COMLEX Level 1?

Yes, 450 is the standard target. The NBOME's 2021 poster found that a COMSAE above 450 corresponds to a 99% or higher chance of passing COMLEX Level 1. A 450 cushion gives you a roughly 50-point buffer above the COMLEX passing score of 400, which absorbs most of the day-of-exam variance. Two consecutive COMSAEs at or above 450 in the final 2 weeks of dedicated is the green light most tutors and DO programs use to call a student safe to test.

What COMSAE score is required to sit for COMLEX Level 1?

There is no required COMSAE score on the NBOME's side. The COMSAE is a practice tool, not a gate. Some DO programs do impose internal cutoffs (450 is the most common school-imposed gate, with some programs at 500 and a handful at 425), so check your program's policy. The COMLEX Level 1 itself has a fixed passing score of 400 on the 10 to 999 scale, with a national mean around 500 and a standard deviation of roughly 85.

What does a 400 COMSAE mean for COMLEX Level 1?

A 400 COMSAE corresponds to roughly a 94% chance of passing COMLEX Level 1, per the NBOME's 2025 poster. That sounds reassuring, but a 6% fail rate is a real number when you are the one walking into test day. Most students with a final COMSAE around 400 still benefit from another 2 weeks of focused preparation to push the score above 425 and the trend upward, especially if there is any history of testing anxiety or a previous score drop on standardized exams.

Can I pass COMLEX Level 1 with a COMSAE under 400?

Yes, it is possible. The NBOME's 2021 poster found that a COMSAE above 350 corresponds to roughly a 75% chance of passing. Plenty of DO students have passed COMLEX Level 1 with final COMSAEs in the 350 to 400 range. The honest framing is that the further below 400 you sit, the more variables (anxiety, qbank percentile, content trend, school deadline) need to break in your favor on test day. Postponing 2 to 4 weeks usually moves the score into a safer range, and burnout starts to outweigh extra prep time past that.

Why is my COMSAE score so different from my TrueLearn score?

COMSAEs and TrueLearn self-assessments are different test forms with different scoring algorithms. The retail TrueLearn self-assessment generates a three-digit score and a "percent chance of passing," neither of which closely tracks real COMLEX outcomes. The TrueLearn percentile (not the three-digit score) is the only TrueLearn output worth anchoring on. On COMSAEs, the score scale is the same as COMLEX (10 to 999), but variability between forms is real. Anchor on two recent COMSAEs rather than a single TrueLearn score for the cleanest read on readiness.

How much can my COMLEX score drop from my last COMSAE?

For most first-time test takers without a history of testing anxiety, COMLEX scores land within 30 to 50 points of the final COMSAE in either direction. For students with a documented anxiety pattern, drops of 50 to 100 points are common and historically expected. If you have previously dropped 50-plus points from your last COMSAE to your COMLEX score, the buffer rule we use is to add the gap to your retake target. A first attempt of COMSAE 430 to COMLEX 380 means a retake target of COMSAE 480 or higher.

Should I postpone COMLEX if my COMSAE is below 450?

Maybe, depending on the rest of the picture. A 440 with a clean upward trend over the last 4 weeks and 2 weeks of dedicated still ahead is usually a "stay on plan and trust the trajectory" situation. A 380 with a flat trend over 6 weeks, a previous score drop, and a school deadline is usually a postponement conversation. The decision is built from your recent two scores, qbank trend, anxiety self-assessment, rotation or LOA constraints, and confidence read.
