I've been avoiding the diagnostic test the past few days but I finally did it. I'm disappointed in myself but I won't waste any time on self-pity. My problems are 1, lack of recall because I haven't revisited these topics in a while. 2, My hands are very slow with desmos and I waste a lot of time plugging things in. 3, definitely lack of practice. I've busied myself with AP physics +AP bio so much that I barely made any progress on my SATs. That's why I'm gonna be doing loottsss of practice and improve as much as I can!! Good luck to everyone.
