The most challenging part of Forensic Science is that this field is constantly changing, but that is what makes it so exciting!
Forensics includes the physical sciences as well as computer sciences. You can get a solid background in one or both. What are you interested in?
My experience is in digital forensics which is a branch of computer science.
Maybe consider looking at SANS institute (google SANS website) to see if you like computers and computer forensics.
Victoria recommends the following next steps:
- Visit SANS website
- Determine if you like computers or if you like physical science: things like chemistry, math, biology
