Revision Advice

I currently revise (also at school every day)
2 Hours on bus (morning and afternoon)
2 Hours at Home
1 Hour before Bed (daily recap)
I spend free periods and private revising also.
I recap the months revision on Sunday and the weeks revision on Saturday

I do this every day of every week and also am eating healthy and working out.

Is this revision plan good enough to get me A*A*A*

And does anyone have any tips for studying and a topic that I should do myEPQ on that allows for high grades,, thinking of doing it on space
