    You should buy a good textbook or go on to a website like Khan Academy. There you can watch videos on exactly how to do it and then practice some questions afterwards.

    Well, it depends on where you are actually losing your marks. I tend to write down al the formulae at the side of the page. read the question, write down the formula I need underneath it, and underline all the data the question gives you. One I have done this, I write the data in the formula, rearrange where necessary and input it into my calculator. I have been told to always give my answer in full, then write to 3 significant figures.

    Just have a method that you are used to and that you use every time. To practice your approach do lots of past papers. My teacher has me doing at least 2 past papers a week. You can use papers from previous specifications as well, it is all good practice.
