Hi Soubhagya,

So, to start with NEET preparations, make sure you know what's the syllabus of NEET. I would suggest you to get NCERT textbooks of class XI and XII as most of the portion is based on it. Nevertheless, refer to some reference books.

Start preparing the chapters in each subjects one by one thoroughly. Make sure you know each and every concept and understand it. Once you're done with chapters, start answering weekly tests based on each chapters to test yourself if you are prepared for the particular chapter. Next, head to tests where in 3-4 chapters are combined. And at the last answer a full syllabus paper. Solve previous years question papers and also sample papers as much as possible so that you can get a brief about the paper pattern.

All the best!
