This.
Take time to prepare adequately, retake, and apply next year. It'll be worth it to save your money and anxiety, and besides, this will give you time to make sure you can bet on your scores before you sit again. Good luck!
I think if they can retake by Sept and do well, they'd be fine applying this year. I wouldn't apply now though, because I don't know if there is a school with a cutoff at or below 4 for a subsection score.
That said, the last date this year is like the beginning/middle of Sept, so unless things get turned around fast, I doubt it would make sense to retake that quickly. The late January MCAT is probably too late for this cycle too.
New schools were all at the average for all other DO schools stats wise it seems for this year.
We won't know this for sure until the matriculant stats come out around Dec/Jan.
I don't know why so many people score so far below their AAMC averages. I took the entire time on all my practices on every section, never finished early. On my real MCAT, PS was more detailed/slightly longer, VR easier but a bit longer, and bio comparable. I scored 3 points above my average.
You are not representative of most test takers. Most people are more comfortable when taking practice tests (especially if they are at their home on the computer they are most comfortable with), than they are on test day. That usually means lower or at least equal scores. Plus, there is an issue of simply being lucky or unlucky and having more or less, respectively, of the material you are most comfortable with on the test.
Is medians be up? My 2011 us news book of med schools has just about every DO school median to be 8 per section, so a 24 total. Maybe the top 3 have 9 medians but majority are 8.
Besides the fact that the DO matriculant MCAT averages have gone up by ~1.5 points since 2011 (not counting last cycle, which should show even more of a rise), US News and Report of med schools tends to use already outdated stats for a lot of the DO and lower/mid-tier MD schools. By the way, the total median MCAT score for DO matriculants in 2012 was 27.
I wouldn't rely too heavily on that data for predicting the results of this cycle or future cycles.
That said, a 24 doesn't mean there is absolutely no chance. Its well below average (by a good 3 points), but at the less competitive schools, it may be just fine considering all else is good and lots of waitlist movement. Afterall, a decent amount of people get into MD schools with 28/29s.
