Dear Aspirant
Congratulations to you for securing such a good score in the JEE Mains examination. According to the marks mentioned by you in the question your percentile would be around 99.7-99.9 which is quite a remarkable percentile. Ranks and percentiles depend on various factors like difficulty of the paper, number of candidates appearing in the JEE examination and also marks obtained by them so seeing the previous year trends your rank would be around 600-900 in CRL. Your rank also depends on the category in which you have applied for. Please do not demotivate yourself and wait for the official results.
All the best
