I am tentatively planning to take Kaplan janury-april and take the mid may MCATs. Is it common to decide to post-pone the mcat in may, if my practice scores are not high enough or I am not yet confident enough that I will score well? Is it a waste to pay for this Kaplan session (Jan- April) if I'm not fully sure I'll take the MCAT in May? I'd probably take it that summer if I decided not to take it in May...
