You are going to need at-least a 4.0GPA to get into a good college. Take classes in law enforcement, be in good physically endurance, I would say you’d need atleast a Bachelor or Masters degree to be in either of these.

The better your mind is, the better you’d investigate. Keep in mind, you won’t be hired right to a fun job, you may have to work in an office for a few years before you ever see real action.

Have good Science, and Math skills. Be physically well. Have from 4-8 years of college, with extra courses designed just for these agents. Be good with geography, and decision making. Learn to use weapons.

I hope this helps, and good luck.

The other issues are much more problematic.

Your cumulative GPA is your GPA from all of your career at the school averaged out. If you had a 3.0, 3.0, 4.0, and 4.0 (assuming equal number of credits each year), you would have a 3.5. Once you are below a 4.0, the only way to get to that mark is if

1) They round up or

2) They have classes which are worth more than 4.0.
