I know a current third year student there was accepted with a 494. The last application thread had people accepted with 496, the one before that had 497s and a 498, and plenty with 499. They only require a 499 MCAT for the guaranteed
admission from their SMP. And just thinking about it logically, if their average matriculant has a 501 (you can find that on the FAQ of the admissions site), that means plenty of people have below that. Many of them probably balanced out with higher stats, but a lot of people don't share stats even on here. Admissions is definitely case-by-case regardless of MCAT score, but LMU is definitely not unfriendly to lower MCAT scores.
Not LMU-specific, but the
2018 matriculant report from AACOM showed >25% of all matriculants had a <501 MCAT.
