I did a little research for you and I have two links that should help you out with your questions. Both of these sites answer the questions very clearly
I think it depends on what kind of forensic science field you choose and also where you get your job when you're ready.
Michael, I thought I'd give you some more information that would help you out if you decide to go into forensic science.
If you look at the links at the top of the page, there is a link titled CSI Shop. There is a lot of learning material there. When you click on that link and get to the shop, look to the left and see the column with different subjects. Go down to the one titled, Science Education. You'll find a lot of items there that will help you be prepared ahead of time.
Check it out.
