sure! for the exam i struggled a bit in biology, mostly upon animal kingdom questions, for physics it was relatively simple make sure you keep newtons laws of motion and thermodynamics in mind as most of the questions are based on that. For chemistry focus upon the common names of organic acids (like malic acid and oxalic acid) and their structures.
As for the MMI the questions are v simple but make sure you know what you are saying as they will have follow up questions. Remember the cooler and relaxed you are the better your answers will be. Keep a warm smile and remain composed you will get through it. Feel free to message me on here or instagram (devikaaa.singh) and all the best!!!
