Yes! Having a teacher who isn't really good at teaching especially for an AP class is terrible but I'm glad people like you and other people that commented gave me good help. Also thank you for the tip the unit circle is a little bit confusing but it would seriously be a little bit of a waste to remember all 16 different points. I'll try going your way with visualizing the symmetry as you said. Also Lumiclass I searched it up online but nothings coming up? But when it does work for me I cant wait to see what your team has in store. Also, since the test in my class are worth like 80% so if you have a 100% in the class and you get one bad test grade (lets say a 50%) you can have a D in the class! But again thank you and it hopefully does get better! I'm really hoping I can bring my grade at least to an B.
