can anyone suggest me a time table to prepare comedk and score UPTO 150 marks in one month

To score over 150, you need determination and a lot of hard work. Know the syllabus first. Instead of choosing a random topic from the syllabus, you must break your preparation into sections. Sub-topics from each section should be selected and then strategy on clearing concepts must be made. Make your own short notes if you find anything difficult to understand. Mathematics will be a deciding factor. So write the formulas of all the subjects together and keep it in a place where you can watch it easily.
Never leave any concepts doubtful or unsolved. Once done with the syllabus and concept clarity, you should move towards solving previous years papers. Give mock tests as much as possible. It gives you a detailed idea of the type of questions frequently asked and also the level of difficulty.
Time management is one more important thing you should look upon. Remember that practise will increase your efficiency.
