they only way to improve in mathematics is practice. as you are very poor in mathematics so i will suggest you to give more time and more attention to the mathematics subject. you have to practice more so that you can remember the mathematics. to score good marks in mathematics i will suggest some way of practicing mathematics. first of all find out some chapters which are more easier to you than the others. first solve all that easy chapters. after knowing the method how to solve one particular mathematics solve so many mathematics yourself related to that, if there is any formula for the mathematics then write all the formulas of the chapter in a paper and keep the paper always in front of you. you may write all the formulas for the total syllabus in a page and may keep it in front of you. when you will be confident enough that you covered all the easy chapters then go for the other chapters. try to know the easy method to solve any mathematical problem. always try to solve mathematics yourself without taking any help. but if you fail just take help from book or any teacher and after that again solve the problem yourself. don't fear about mathematics. fear will decrease your confident. always take mathematics as easy subject. just do lots of practice. surely you will get good marks in mathematics in board examination if you study hard and give attention to the mathematics subject Source: http://entrance-exam.net/forum/general-discussion/how-score-good-marks-maths-board-exam.
this is very useful. thanks sir
