well you are not a newbie in here and you know what everyone is going to say . FUll time + MCAT = Disaster , you wont just screw yourself but you will screw up your GPA too . My advice is if you are taking only 12 credits and they are all easy subjects then you can prep for the mcat by just going over the concepts without memorizing everything just make sure that you understand what the book is saying; but if you are taking hardcore classes then dont screw yourself by rushing to the MCAT . People (Including ME) usually rush to the MCAT and when they end up with a bad score they think they didnt do anything wrong .
