Hi! I appeared for jee paper 2 this year and scored well in maths.However inspite of the content here,i also did previous year questions and mock tests.

Extending Gowri Krishna's answer you can now access past year student's works, the best examples and gain exposure to improve your own skills by using these new filters -

It is mandatory to visit all the question. After you have attempted the question go to the last question and click submit. A note will appear telling you do you want to submit the test. Click yes and you are good to go.

Hope this helps.

You do not need to write CET Exam, but filling the CET application form is mandatory.
