prelim results out

Well got back my prelim results today, physics and chemistry... got a c6 and b3 respectively. amazingly it was e other way round for mid years. but oh well physics paper was a killer too... Moreover didnt really prepare that well everything was done half way.
SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO....
i calculated, if i am to prepare for my Os sufficently i should be ahem:

42 days to e first O level papers
60 prelim Papers i have to complete (x2) times over.

42 - 12 = 30 days (12 weekend days)
therefore 30 / 2 = 15 ( 2 times over )
60 / 15 = 4 papers a day!
1 paper approx. 2 1/2 hrs
2.5 x 4 = 10 hours a day! = WOAH!!!!
some kind of endurance run lol... and i have to repeat it twice.

after covering my math and 2 science theres e humanities, think constant reading and revising will do? and how u tackle particular questions... EL is exposure and CLB hmmm.... lol just read both of e books... i lost my sec 3 CLB book. e bookshops dont have them just goes to shows how much they hate CLB.
