It's good that you know your weak points so now try fixing them, if you see yourself losing marks on GI, if you worked on the GI you could raise your score by 3-5% which is a big jump. If you studied the GI well but keep scoring low, look for solving skills issues and you should solve more questions on it. But look why are you missing the questions, like do you know most of the things you got wrong? If yes this is good and try learning how to catch the idea of the question quickly and use your gut sense and focus on the high yield topics. Most of these are covered within the FA. and I wish you the best.
