Hi everyone! I’m looking for some advice. I’m debating whether to pursue my dream of studying Marine Biology, even though my undergraduate degree is in Criminology. The two fields aren't directly aligned. I graduated with my Criminology degree three months ago, but it wasn't my dream program; I only chose it because I felt overwhelmed at the time and didn't feel like I had any other options.

1. What subjects will I need to take?

2. Is it difficult and how long will it take?

3. What careers will I pursue?

All your advice are much appreciated.
