Please review my revision plan for my gap year - 2025 entry

So I'm resitting A-level bio and Chem for the next cycle i.e. to go into uni in 2025. My plan is starting today from Monday - Friday I will begin my day with at least one hour at the gym then when I come home I will do 2 lessons of Biousing pomodoros then have a 15 min break after those 2 sessions and then 2 more lessons for chem so 4 lessons in total and about 4 hours of work in total giving me the rest of the day to spare. If I stick to this monday-friday according to my calculations I should have covered all the content by the end of August 2024. I will be working 12 hours a day on the weekends to make some money and to give me a break from revision. In October I will apply for MPharm to unis and prepare for interviews and do as many past paper questions as I can. In November I will work full time (12 hours 3 days a week) to make more money and focus on interview prep, past papers and recaps until exam season. Around December time I'll do slightly less revision i.e. instead of 4 days since I'll be working 3 days I'll do 3 days revision and have one whole day off to keep my mind fresh but when I get close to exam season I'll reduce my work hours and stick back to the original Monday to Friday revision routine. How does this sound is it realistic?
