I'm not sure, thinking about 3-4 hours per day.
I do English Lit, History and Maths, so it should be manageable, maybe I need to put in some more on particular days.
I agree with the previously established concept of revising by deciding on what is to be achieved within the revision session, rather than simply attempting to fill a particularly stretch of time.
Maths is the hardest for me, but I really need at least one A grade in order to attend my University of choice, at least, that is what I have been told.
My problem is that I lack the concentration necessary to study for long periods of time, I turn to forum boards such as Reddit (and even TSR itself can be viewed as a means to procrastinate), rather than simply buckling down and performing maths questions.
Does anyone perhaps have any tips that I can use to retain my focus for extended periods of time? They would be much appreciated.
