JEE Main

I think 230+ will be a secured score.

If your 3rd step of filling the form was completed then you will not be able to appear for 2nd paper.

The answer is absolutely no because if every student should take JEE entrance examination in online mode then there is no concept of keeping offline examination. So, why to choose always online. Go with offline for better performance.

The best option you can choose is offline. You will find many advantages in offline mode examination like ease to solve the questions which you feel easy at first and then you can save time to solve more questions.

It is better if you go for offline because you will get a chance to select the questions in random manner means the questions you feel easy to work with can be taken first instead of going one by one. Another advantage is you can work on the questions first and then answer or mark them on the sheet later before running out of time.

You have changed your board so you should appear for the exam in 2017. You don't need to mark yes in improvement.

To fill the application form of JEE Mains exam you need to have passport size photo, your signature, thumb print and Aadhar card number. During examination, you should have hall ticket of JEE Mains exam.
