NEET-UG I Chemistry QBank

Welcome Aspirants !!!

ScholarWorm welcomes our aspirants who are always hungry for more knowledge. We are here with our Free Chemistry QBank for NEET-UG to help our students to practice regularly and perform at best of their ability in their exams.

Instruction to Create Question Set :-

1. The Test Paper is AI generated.

2. On clicking the button below the AI bot creates a set of 20 Questions from the pool of questions that is being updated regularly by our expert faculties.

3. A Timer is set for each Test Set, once time is up the AI will automatically submit the test.

4. New Question Set can be created by going backwards and repeating the above steps.

Note :- Number of Questions and Timer is not customizable in Free QBanks.
