Oh my. You were doing exactly what I've done in this holiday. Though I didn't watch those, I still spent time on watching animation and reading online comics. But don't worry too much, S.4 syllabus (later you will find) is so easy that only practice can handle it all. Theories in S.5 and S.6 are more complicated and really need your thorough understanding of them all the time. But just take it easy, I think you can handle them too. Okay, I admit what I've just said is more or less the same due to fact that I don't want to do any revision and don't want to be sleep-deprived which of course will harm your skin and make you look elder. (Sigh)
