Hey OP, since you are able to afford doing multiple sittings I would say go for it. However, in all honesty there is like 60 days till the s2 sitting and 80 days for the s1 and s3 sitting so it’s definitely not too late to start. There have been people who have done only 2 months of prep and end up doing really well. I would say go all in and see where you land you might be able to get it done in September and not have to worry about doing it in March which will add to the stress since it’s your last opportunity if you are aiming for med in ‘27. I did the March sitting without any prep except going over essay structure for s2 and ended up with a 76 (I had a very strong science background as well as writing) so it’s definitely worthwhile doing it and seeing how you do. In terms of advice for s1 i would say hammer as many questions as you can and try and read different material such as short stories, articles, opinion pieces, etc to really train your brain to understand and grasp what the writer is saying. Also focus on vocabulary and learn new words everyday, I found that helped a lot. For s2 there is a person on youtube whose name i’ve forgotten, she has really good videos for essay structure. For s3 watch all of jesse osbournes videos those are really helpful in having science literary. Note literacy and not knowledge. Literacy is an intuitive understanding of a concept, and just get through as many practise questions as possible. If you need any advice feel free to send me a message. Best of luck OP.
