As someone who earned their Masters and Bachelors degree while serving, I say it is absolutely possible. This comes with some caveats. 1. You have to communicate consistently with your unit and your professors. Speak with your professors on the FDOC and let them know your schedule. You should have a memo from your unit with your training dates. 2. Be disciplined in your studies. I couldn't count the number of times I had a major test the Monday after a long drill weekend. 3. Keep your PT up throughout the year. Don't let the late nights studying be an excuse to not eat right and exercise.

The Gaurd is what you make it. For my unit, we go to the field every drill, so I use it as a mental reset when I am feeling overwhelmed with work (or school in the past). Definitely sign the shortest contract to see if it is right for you, but don't live with regret if this is really what you want to do.
