While it makes you look better to take bigger course loads, you have to remember that its grades that matter. I rather take 12 credits and get all A's than take 18 credits and get a mixture of A's and B's. A's open doors, its just a fact. I mean my recommendation is just take what you can handle. Me personally I like taking 12 because like a said it allows me to perfect a little bit better. When I first started undergrad I took two 18 credit semesters in a row, and let me tell it was hard(i also worked 25hrs a week). I did alright but I'm a lot better with 12 or 14. My tutor god bless him took 12 his whole undergrad career and only got 1 B the rest were all A's. I don't know what he scored for his DAT but it only took UD Mercy dental school 3 days for them to tell him that he was accepted. Bare in mind he went to UD mercy undergrad like me. Mercy is a tough school. Classes like Organic Chemistry, Genetics, Cell Molec are extremely difficult here. Sorry for the big reply but I just wanted you to know that 12 credits is plenty assuming you get decent grades. Anybody saying that you need more or else you won't get accepted is a falsification. Don't listen to them its all tricknology. A tricknologist will use mind games to convince you that you need to do something else so you might make a mistake and ruin you GPA, DAT, acceptance, life ect. Remember there are only so many seats, and this is competition. Knowledge is GOD, you know what they say "work like a slave eat like a king."😎
