You will not be eligible for admission as preparatory ranks are not considered under round 1. Since you have already qualified to appear for JEE (Advanced), all you need to do is meet the second criterion and apply for round 2, which will be only conducted if seats from round 1 remain vacant.

Yes, you can still get admission in Round 2 if you meet eligibility criteria to appear in JEE (Advanced) and have a valid JEE (Mains) rank. Also, you must have scored 60% or above in class 12th. For SC/ST/PwD category students, 55% or above is required.

Mock test released by organising IITs are very useful in understanding the pattern and difficulty level of exam. However, solving official mock test paper only is not advised. It is recommended to solve additional mock test to score good marks in JEE Advanced.
