Essays can be your best friend or your worse enemy, you may hate them, but it is in your best interests to adapt. In the beginning of the year you will most likely hate essays, but they will grow on you, I promise. They will trigger you with grammar points and debatable answers, but as you learn and as you study they make you happy with free grammar points and the correct debatable answers. If you are bad at the multiple choice then you will have a large chance to increase to your score on your AP exam to bring up your grade.
Do not forget about the most important essay of all time.
