is it worth it?

<p>my expected gpa by the end of junior year(June) is a 3.58 if I take two online summer school classes during the summer.
Do you think it would be worth it for me to take TWO MORE classes so I can raise my gpa to a 3.6 or should I just focus my time on other things such as raising my sat scores?
the down side is that the if I do take the two EXTRA summer school classes then I will have to commit 5 hours a day for 8 weeks and I'm not sure it its worth the time.
please help me!
thank you :)</p>
