Great presentation. I always seem to understand but when taking exams I get nervous especially when running out of time. I need short cuts and quick checks to make sure I get the correct answer if you know any.

At least for derivatives, you can do the problems a lot faster when you learn all the derivative rules and can use them instead of the definition. When it comes to test taking, I know a lot of people struggle, but the most important thing is to stay calm, make sure you answer the easy questions first to get points, and not worry about problems you don't get to, because the worry and anxiety don't help you finish the current problem. But it takes practice! :)
