NEET DLPs should have the mix of concepts and problems. The problem with missing out on problems is that it can cause a lot of error in calculations during the actual examination even if the student can assess the question. The problem with missing out on concepts is that if the questions demand a little bit of thinking outside the box or introduces new criterion previously undiscovered in practice questions, the student will be unable to attend the question. Thus a NEET DLP should have a mixture of both.
