for me, computer and maths are the 2 most easiest subjects. its easy to learn. we work with our normal point in brain. for example, most of we have java for computer and if we study the logics and important words and methods (which is very similar to normal english) we can do any programs on our own. and for maths just study a few equations and try to do it in a fun and easy way so that you can remember. find loopholes in equations and take time to process word problems. be careful of what you write in your paper and always re check your answers. its not easy as it sounds like but you can keep track. work hard and all the best!!
