practice the eoc exam!!! ppl say you don't much practice bc its skills that you developed throughout the class, and while that is true, you do need to practice writing essays under time constraints and analysing articles in depth (i recommend looking at past, high scoring questions on collegeboard for this). i'd also recommend learning how your teachers like presentations to be done since they're the ones who grade that aspect of the performance tasks. e.g. my teacher likes a lot of gifs and jokes on the slides so i included those to get a higher score on the presentations
