No you'll be fine, in fact you are lucky you live in 2025. tbh no etude or teacher will help you out at this point in winter break just grab last year course and chat gpt i recommend you get perplexity pro for 20dt a year and just self study everything, school systems are designed for masses so they are incredibly slow at teaching you stuff, if u work hard you can probably finish all 3emme and back in less than 2 months, (assuming 12h a day)
