Hello Sreekanth

Greetings

Your percentile score is only 9.089 It means 9.089% student of the Total student appeared for the Exam are Behind You Therefore 90.911% students of the Total students appeared for the exam are Ahead of You, Therefore Your calculated Approximate rank is 794988

But Note that this is Not Your Final rank Your Rank Your Rank will change Because It depends on Performance of You and Others in the JEE Main April, And the final Rank would be calculated Based on comparing Final percentile ( Whichever is Higher in Both the attempts if any) of all the students

Your rank is Not Good and You should Try in the Next attempt of JEE Main which is JEE Main April and Try to perform well, If You don't appear for JEE Main April You will not be able to qualify JEE Main and will not be eligible to appear for JEE Advance

Here are Few Tips for You in the Next attempt

1. You should Focus on NCERT Only and Don't Go for other Books

2. Solve ALL Previous Years Questions of JEE Main and attempt as many as Mock tests You can

Hope this Helps All the Best
