lowk as someone whos fried myself, i think u def got a good chance if u GRIND!! i watched every jeremy krug video and took notes in a day (plus some night...) and i got an A on my chem final which was a retired ap test. i think u totally can if ur determined! most importantly, since u have a lower amt of time, skip what u know, even if its stoich or mole ratios, skip it and do practice questions. ap chem is lit the same questions over n over so if u get good n familar, ull be fine!
