You may start your preparation by watching success stories of previous year candidates. You can note down their preparation strategy, Mock test followed by them etc. Understand the syllabus first, Then draw a plan (plan include short term- daily portions to be covered + Long run ie In a week you need to complete this much of portions like that ). Try to stick to the plan , follow it strictly. Clear All the basic concepts firsts, then practice previous year question papers of at least 10 years. Give mocks,  Analyse your mistakes. You can definitely clear the exam. Suggested YouTube channels like Wify study, Un academy etc. Stay focused, prepare well. You can crack the exam in one go itself. If any doubts, pls feel free to ask !

Wish You Good Luck !
