NEET Exam Smart Learning - Videos & Notes

NEET UG Exam Smart Learning has videos, study materials, notes and other help keyword wise and topic wise from large pool of knowledge.

Use NEET Smart Learning to know what you do not know. NEET UG Self Assessor helps you to know what is still required to be learned.

How to NEET Exam Self Assess and Learn

Select any NEET UG Exam subject, topic or keyword of your choice.

Set your own number of questions and time

Answer 100% of questions correctly

If you do not know the answer, you can refer to NEET Exam help, books, video, text, teacher or google search. This is not a test. It is process to identify gap in your knowledge and fill the same

There is no need to set large number of questions. Just set it as per your need and time. It can be just one question also. Learn it seriously or at leisure. Learn while eating, traveling or watching TV. Learn on your tablet or mobile

If time is sufficient, repeat with new set of questions.

We can provide readymade explanation for correct answer. But that may be biggest block in your learning process.

The content of NEET UG study material is large. As such we are only placing below a part of the same for review of our readers
