THx for all the advises! i am also a weak sejarah student, i bought the sejarah comic book from popular the title of the comic is 'syok komik', its preety good, i can understand more now

but some of the parts are damn confusing... but overall its good!
Geografi, im previously weak at the maps but after my bro taught me the specific places for the maps, im ok at it already...
the thing that im concerned is that, kh.. I suck real bad at the teras part and also the akaun part!!
P/S: my school exam is coming so soon!! 6th March

oh! and, can any1 help me with the science form 1 chapter 4 part? about the elements,compound,mixture part.. i dont understand a single thing! and also the maths form 3 chapter 4, the median part! :S
thanks in advance
Elements Elements have one type of atom. They are unable to be broken down to any simpler form.
Examples of elements : Sulphur, gold, platinum, lead etc.
CompoundsCompounds contain two or more elements that are chemically combined. They are only able to be separated through chemical methods(electrolysis). Heat is released or absorbed in the forming of compounds. They are combined in a fixed proportion.
Examples of compounds : Water, salt, carbon dioxide, methane etc.
MixturesMixtures contain two or more elements/compounds that are not chemically combined. They can be separated through physical methods(distillation, evaporation, magnetic attraction, sieving etc.) Heat is not involved in the forming of mixtures. They are not mixed in a fixed proportion.
Examples of mixtures : Sea water, salt solution, blood, air etc.
For KH, have a thorough understanding of all the chapters in Teras as the first 50(or was it 40?) questions of the KH paper are based on Teras. Buy those Bank Soalan books, do the practices in them and you'll be fine. The questions in KH are often recycled ones. They don't differ much from year to year.
For the Akaun part, I would advise you to do plenty of exercises on that topic too. However, make sure that you fully understand Simpan Kira before attempting it or you'll just be wasting your time.
Median is basically the middle number of a given set of numbers. For example, {2,3,4,5,6} Therefore, the median of the set of numbers will be the number 4. Keep in mind that the numbers are not always in order. They can give you {8,3,2,6,7} and the first thing you need to do is to rearrange the numbers to make {2,3,6,7,8} Then you'll see that the median is 6 instead of 2.
*Disclaimer: From this part onwards I'm not quite sure if it's accurate or not. Please refer to a reference book/textbook to double-check.
Sometimes, they can also present the question in the form of a table in Paper 2 of Maths. You will have to calculate the total in the table. If it's an odd number(let it be x), the formula to calculate the median is (x+1)/2. Then with the obtained answer, compare with the subject given on the left side of the table and the subject that includes the answer in its range is the median.
For even numbers, (let it be n), the formula is (n/2)+1 AND also (n+1)/2. Do the same thing for even numbers.
