It is really hard to say. Based on ability so far a 240 might be up near his limit maybe a 250. Got to do more work first. Can you, yes.....will you do not know. 9 weeks is more than enough time.
E. Not enough info to answer the question.
This. 9 weeks of intensive study is probably enough to get a person to the peak-level performance that they can reach. However there's no guarantee that that peak is necessarily 240+. Some people have test anxiety, others just don't do well with standardized exams, others probably didn't learn the material well enough in class and it would be unrealistic for them to expect to fully understand everything during dedicated review.
Best thing to do is to kick review into high gear and follow a plan. I'd personally aim for something like FA 3x, pathoma (book only with notes) 1-2x, UW 1-2x at the very least. After you've done UW 1x, I'd consider adding a bit of USMLERx qbank to mix with the second pass of UW to keep getting some fresh questions. Then 1 practice test every weekend starting after your first pass through FA.
So a sample plan would be:
FA: 1st pass: 3 weeks, 2nd pass: 2 weeks, 3rd pass: 2 weeks (7 weeks total)
UW: 1st pass: 4 weeks (2 blocks a day), 2nd pass (incorrects/marked): 2-3+ weeks flexible depending on how much you marked/got wrong
Pathoma: aim for 1 pass every 4 weeks (1 section every 2 days)
USMLERx: concurrent with 2nd pass of UW, no need to finish
NBME/UWSA every weekend after the first 2 weeks.
6 days of studying a week, 1 day off.
Evaluate after 5 weeks. At that point you should be done FA 2x, UW 1x, Pathoma review 1x, and 3-4 NBME/UWSA. So you can judge based on the trend of scores in UW and the practice tests whether you see an upward trend. If the trend is steady up, then continue on schedule. If the trend is peaking then wait another week and re-evaluate. If it's still peaking, consider moving test up. Re-evaluate every week.
