Is it too late to self study Calc BC?

I’m in Calc AB right now and have coasted through the class with no problem. I fully understand limits, derivatives, integrals, etc. and have kept a solid A throughout the year. I wanted to wait until after 1st semester to see if I wanted to self study for Calc BC. Unfortunately, I “accidentally” ended up waiting another 2 and a half months and now I’m stuck in a tricky position. Should I start cramming everything in for the Calc BC exam (running a risk that I might run out of time or not even understand the content), or should I scrap the idea and stick with the Calc AB test?

don’t worry, it takes 60-100 hours to master Calc Bc including the ab portion which is 60% of the test. So, you should be fine as long as you do about 1-2 hours a day just to be safe starting around this time but not after march.
