Hello Ayush,
It's never too late to start. Life always gives everyone a second chance and it's upon us that how we are utilising that chances. Whatever said and done, it's done you cannot change it. But what you can change is present and future. Work harder in your present to make your future bright. Thinking about the past and worrying everytime will take you to nowhere. So change your worry time in study time. You have already wasted so many years and now again you are wasting your time by thinking about the past. Stop wasting your time and start studying. Because hard work only will take you to the doors of success. Start writing your problems and how are you feeling in a Journal and you will see that while writing those problems you will surely get a solution to that. Talk to those people who believe in you, who eil motivate you but firstly you have to believe in yourself. The time you will start believing yourself that yes you can do it, half things will be done there only. So start your preparation and stop wasting time.
Follow some tips to start your preparation and do it well. Firstly you have to read the syllabus of the exam very thoroughly and need to understand the syllabus. Secondly you have to analyse the previous years paper's of the same and you have to understand the demands of the questions. Next, you have to decide your booklist and stick to that. Follow one book for one subject and revise it multiple times. Then you have to practice a lot of questions and give a lot of mock tests and analyse those mocks and try to understand where are you going wrong. Last but not the least you have to keep faith in you.
All the best!
