its not worth it
just starting revising around may /april and you can easily get a *
meanwhile try doing 20 mins a day at lunch or break
that's 100 mins a week and it seems like nothing cuz its spread out
so 100 mins a week, theres like 25 weeks left or something idk
that's 2500 mins just doing random work at lunch
will save u a hell of a time at home
Are you cut out for it?
