Science kills....

Today, i got back my physics paper and last week i receive my chemistry paper. At first, i thought chemistry is quite interesting but slowly, i am starting to get things mixed up, confused in chemistry causing me to get horrible results since the very first chemistry test... Today, when i receive my physics paper, i know i am careless in the paper therefore i got horrible results. Well, i failed both papers by 1 mark in overall which is 2 marks. *FAINTED* Don't know how or what to do. I think i should start doing test paper but haiz...don't know what to do about it. After Jolyn's tutoring, i manage to have a better understanding on chemistry but i still got a feeling that i am still lack of something in chemistry. Well, as long as i make sure that my physics do not have careless mistakes and make sure i don't go kuku, i believe physics shouldn't be a problem but what i am worry about chemistry... Well, sciencce stands a overall higher percentage for the streaming result so if my science is so horrible and terrible, it will surely pull down my overall percentage and my class and school ranking will surely drop and by then, i think i will really go kuku. All my hopes in getting a higher ranking or should i say more A's are all gone just because of SCIENCE SCIENCE SCIENCE!!! OMG!!! My brain is going to burst because of science and it is just so important yet i am so weak in it. TELL ME WHAT TO DO LAH!!! I AM GOING CRAZY!!!
