A level help

I have decided to take maths further maths economics and an epq and I want to achieve an A* in all of them (or A in further maths due to the pure difficulty) I have thought of ideas on how I will achieve these days . I’ve decided to start revising and reviewing from day one not loads but consistently as I dont want to do to much . I have thought of the idea of going to my maths /fm lesson then when I finish it go to private study or at home watch a video on it finish if the textbook questions on it to a high standard then a couple days later look at exam questions on it then I make a logbook on how I feel on the topic and I use the forgetting curve mechanism to known when to look at it again . For economics I will go to a lesson , get the notes , go to private study or at home I’ll read over the notes watch a YouTube video on it and link to real world so I understand it . Then I make flashcards on it then do topic questions on it then later do exam style questions and again make a logbook for it so I know how I feel on it and when to revise for it . How did every go about making there on revision schedules and timetables and how much and how did they revise and do they have any other tips for my sixth form life and what they think of my routine and how to improve it as I am hungry to achieve after not getting the GCSEs I wanted.
