@himikie if you would want to enter a SMP this fall (2020), APPLY NOW! There are still a few places that are accepting applications (potentially until July 1? unsure), and many of them do not require an exam score. If you wait for your MCAT to come back in August, you will probably be too late to enter this September.
Otherwise, the wise
@gonnif usually advises to wait to apply to medical schools until
after you complete your SMP. So if you entered the SMP in Fall 2021, you would wait to apply to med schools until May 2022. That way, you have your SMP grades and the strongest possible application going in to the cycle.
