1. Do well first semester so that you won't have to study much for the finals.
2. You have an A at the beginning of second semester. Work on time-management and try your best to keep up(probably best to give up a lot of other time-consuming activities). If you fail, you have the rest of the semester to catch up and hopefully win back the A.
That is how I see it and I had to do a different version of it even before I joined robotics because I was in field show & marching band. It works, just don't kill yourself over having few Bs on your third quarter grade and all shall be fine~
