First of all, I'd suggest you to learn basic mathematics as it is needed in each and every section of physics.

Don't try to memorise the formulas, just try to derive them once. So even if you don't remember the formula, you'll be able to derive it on the spot. I had applied this method and seriously it helped me a lot because I didn't have to cram up such dangerous formulas.

Practice Physics daily. This is the need for the subject if you have no idea about this subject Don't try to solve each and every MCQ books, as 90% of the questions are almost same in all the basic books. Just prefer one book and make sure to solve its each and every question. If you have finished one book then go through the other but remember the second book should be of higher level.

Make your theory strong. I repeat again make your theory part strong. Without theory you'd never be able to get the practical knowledge and Physics is all about practical knowledge like how much you can imagine on the given topic. Just make sure to read theory.
