AP Biology exam

I do not think I did as good here as I did in AP Chemistry. But I still think I passed. Here is a summary like the AP Chemistry one: AP Biology has 4 big ideas: Big Idea 1 Evolution and diversity, Big Idea 2 Free energy and metabolism Big Idea 3 Information and genetics and Big Idea 4 Systems and their interactions. The Exam has 2 sections : the Multiple choice ( which has Grid in questions ) sections and the Free Response section. Each is worth 50 % of your grade and each is 90 minutes. There are 63 multiple choice questions  ( with 4 options ) and 6 grid in questions ( which require numerical answers ). Calculators are allowed here as long as they are basic ( not scientific or graphing ). The Free response section has eight questions, 2 long 6 short. There is a ten minute reading period at the start and 80 minute writing period after that. Each Long question is worth a maximum of 10 points and each short one varies between a maximum of 2 ,3 and 4 .
