self-teaching a-levels study plan help

Due to personal circumstances, including some significant health complications, I had to drop one of my A-levels (English Literature) midway through Year 13. I plan to self-teach a new A-level during a gap year (I could carry on with English but I hated it so much I don't think I'll have the motivation to study for it). I'm currently sitting exams and expect that I’ll need to resit my other two A-levels next year as well. My current subjects are Biology and Psychology, and the subject I’m planning to self-teach is Sociology. This means I’ll be revising two subjects and self-teaching one. I plan to begin studying as soon as my current exams finish (on June 18th). Could anyone advise me on how best to structure my time? How many hours per subject should I aim for each week? I know the workload might be pretty heavy. Any guidance would be greatly appreciated - thank you!

I'm currently self teaching sociology! What exam board are you doing? I dont think I could give any advice atm as I havent sat all my exams or got my results, I would say the best thing to do would be to see if you can resit year 13 and then do it that way? Then your teacher could help with the year you missed out on
