what is the best way to try to get accepted into law school?  

I live in Australia so there may be a distinct difference in how the system works; however, I think that you're very much on the right track. Undertaking a bachelor's degree in criminal justice will highlight both your committment to higher education and your passion for the subject mattet; so prospective law schools are sure to look on that favourably. Any other academic excellence - certificates, awards, etc. - that can make you stand out from the pack are also highly recommended.

If it's not too intrusive a question, may I ask what institution/website you are studying criminal justice through?

All the best with your future studies in law.

Start by getting your GPA up to at least 3.8. 3.3 is a joke. Sorry, but it is. You should strive for 4.0 from now on and it will level out your bad 3.3 grades.

Work on your grammar. It needs to be better than perfect. If I were to use this post as an example, you would flunk 6th grade.

Make sure your on-line school is accredited. If it's not, it doesn't count.
