Hello. This is my first post on here and here it goes. I am currently a software engineering working on my masters in comp. engineering. (2 classes left) However, my career doesn't make me feel *important*. Not only that but I want to have a lifestyle where I feel like I have helped somebody. Money/respect is also a plus. Ideally, I would like to work in the US for about 8 months and spend 4 months travelling to different countries helping over there. My gpa in undergrad is 3.96 and my grad. gpa so far is 4.0 I haven't taken any prereqs for medicine except couple of physics classes. I took AP chem in HS and really enjoyed it and was actually good at it. Currently, I am working full-time and would like to see if pre-med is for me. I am thinking about taking biology (subject which I hated in HS) and see if it will excite me or not. Right now, I make more money than you would as a resident so not having cash flow like I have now will be something completely new that I will have to get used to. Any comments/suggestions on my thoughts above? Few more questions: 1. DO vs MD? Does it really matter? Isn't the curriculum the same in both type of schools? 2. Do MCAT scores have an effect on what type of residencies you can get into or would that be based totally on USMLE 1 & 2? For instance, if someone wanted to go into surgical residencies where it is pretty competitive, would it be based on MCAT scores also? 3. What do you think about taking some science classes at the univ. that are taught in med. school (before going to med. school)? Classes such as biochem, AP, cell/tissue biology? Thanks.... by the way, I am 25 yrs old and have been working for the past 2.5 years in this crazy economy.
