“I also plan to be Pre-Med and am wondering about the impact on the workload as well as how possible it is to be an IS major and Pre-Med.”
There is no problem at all with being an IS major and pre-med, because pre-med is not a major - it’s just a sequence of courses that you need to take to meet the requirements for admission to medical school (and have sufficient background to get a good score on the MCAT.) You should have no problem fitting the requirements into your schedule while getting your IS major done.
By the way, I’m impressed that MacAdmissions responded directly on this forum. I wish the other LACs had someone watching their forums and responding where approrpriate.
