Yes, they do. But, one cannot predict it because it is the NTA who sets the question paper. The NCERT single-handedly is the star textbook to refer to while preparing for the NEET. The questions in the NCERT might not come the way written in the books. If you are thorough with the NCERT you are prepared for the examination. Nevertheless, NCERT alone won’t do the trick, candidates also need to refer to other textbooks available out there to have a strong command over the subject and fully prepare themselves for the upcoming exam.
