I only took a class this session and the reason is to spend alot of time to study for DAT, because that is my week part from last cycle, however some friends are scaring me and telling me that its really bad to take only 1 class is that true?
It's probably safe to say more than 1 class a semester is better than just 1. Adcoms pobably like to see that you can handle a rigorous course load and be successful.
Its probably too late now to do anything about it anyways even if it was as you say,bad. If you did it for multiple quarters it would probably raise an eyebrow. Get a great score on the DAT and that will overshadow quite a bit in your application.
