Aiims, pgi, jipmer pg exams and neet will check thoroughness or ur basic understanding of your concept in every subjects. The only advantage of neet from other institute exams is no negative marks and u have 5–10k seats. Read your text properly.. Just don’t read for exams or important questions for your internals…
