Hello,

The National Eligibility cum Entrance Test (Undergraduate), formerly the All India Pre-Medical Test, is an entrance examination in India for students who wish to study undergraduate medical courses and dental courses in government or private medical and dental colleges in India.

Try to reach on time as many new procrdure have to be followed due to current COVID19 situation. Also you can take book with you if you want to revise on way.
You can have lite breakfast (adequate so that you don't feel hungry during the exam) and carry a snack with you onthe way as the crowd will be huge and they'll follow all checking procedures so it might take time.

Hope this helps
