Marine reserves during summer and college in the fall?

I'm currently a high school senior and I was accepted to the university of south Florida on a conditional admittance where I have to attend summer term b and maintain a 2.0 gpa to make fall term, I wanted to become a marine after college when i had secured my bachelor degree and I was looking forward to going through PLC, I was aware the reserves could pay college but I wanted to earn my undergraduates on my own because I felt like i would be milking the system like most of my friends are doing by joining the army for benefits and money not joining for the right reasons, everything was going well till my parents decided they refuse to pay my college for multiple reasons now I'm stuck I do not want to take out multiple loans for my undergraduates and now I'm considering joining earlier because I'm really stuck now I'm curious is it possible to attend boot camp in the summer and go to college during the fall as reserve
