Dear aspirant,

As you have mentioned that you have secured +30 marks in JEE mains and taking into consideration that you belong to ews category so let me tell you that your prediction is 60 percentile and your rank would be around 4.5L.

In this rank you can expect any colleges through josaa so I would suggest you to keep other private colleges as a backup.
