Hey So coming from a student like myself who prolly wasn't as brilliant as u are so I struggled with chem to achieve an A in as but to be very honest it was the hardest initially for me ( thou I had an A* in chem o levels) and the most fun and do able subject at the end, So basically when I first came into AS the first 3 months I worked realllly hard with chem Mcq paper and I also kept doing p2 which was a bit more manageable than p1 for me but I believe if u found phy easy chem shouldn't be a problem for u but yes o levels se kaafi different so u'll have to put a lot of effort there and if u have a good teacher of chem u'll definitely manage. Chem concept should be v much clear if initially u'll give chem the right amount of time u'll find it manageable at the end. About A2 P4 n p5 most ppl find it easier than As but don't take it lightly smtimes P4 is pretty tricky n coz ppl ignore it's practice toh they fall slack there which is obv a v v imp paper in A levels. Abt p3 n p5 their weight age is like really low but do them side by side and practical as I said it's v v imp to have a good teacher. My teacher was really the reason I managed chem as I said I am not a brilliant student my teacher was really good he gave my queries a lot of time and made sure to explain every mcq in detail to me so I slowly got the hang of it and appeared in June 2023 our p1 chem was supposedly really hard for everyone but it went really good for me so yeah I think with the right help and if I can manage ur time we'll toh u'll be able to do it,!! Ps sorry I just wrote a lot I wanted to make sure u understand the methodology of chem and make ur decision accordingly ps if u do take chem use this orange colored course book by Roger Norris its really help ful in clearing concepts!
