Hi

The eligibility criteria for BTech in Jadavpur University states that if you're a general candidate you need minimum 45% aggregate in your PCM taken together or else for a reserved candidate it is 40%. Besides, you need atleast 30% of total marks in English. See if you qualify for the above.

Check this link to get a better idea about your query: https://engineering.careers360.com/articles/wbjee-eligibility-criteria

All the best.

Hope this helps.

Cheers!
