Kolkata

Yes, of course. Why not.

Hi, I am suggesting you this link, which has colleges according to ranking, fee structure and student reviews (students from that institution). https://googleweblight.com/i?u=https://www.shiksha.com/medicine-health-sciences/pharmacy/colleges/b-pharma-colleges-Kolkata&grqid=LxsFtUCU&s=1&hl=en-IN
All the best.

You can take admission into private colleges in Bengal with your JEE Mains score. WBJEE counselling will start from 28th May, and so go for the counselling with your JEE Mains score. Hope, it will help you, if you have further doubts then you can ask in comments. Thank you.

No, if you belong to a general category. Otherwise, you can go for management quota, and so if you have enough money (INR 10 lacs) they you can go for it. But, I will personally not suggest you to invest that amount money. Rather, I will suggest you to take a drop and give whole 1 year preparation. That will be the best option, as with this rank you will get a very bad college and I will not suggest you to do that. So, give yourself one more try okay. Come back stronger. Best of luck. Hope it will help. Thank you.

If your location is your priority, I would suggest google some of the good universities which accepts JEE Mains marks. Though, moving out of your location, you can get any NIT accepts top 4 or 5. Some better suggestions are BIT-Mesra, NIT-Bhopal, NIT-Durgapur, NIT-Kurukshetra, NIT-Raipur.

The percentage required for participating in WBJEE counselling is 45% with PCM as compulsory subjects which is the only way to secure admissions into the Jadavpur University. Rest, your WBJEE rank will decide whether you will get into or not.

Akash is not recommended for JEE Mains and Advanced coaching else it's advisable for Medical and NEET Coaching only. For JEE Mains and Advanced coaching in Kolkata, you can prefer for FIITJEE, Resonance or Pathfinder.

See, first of all, relax. Life is not just about one exam. Move in to next and I will recommend you to go for a college with less fees. Why I am telling this because you can use that money in your MBA. Yes, if you can tactfully invest your 4 years in CAT or IIFT preparation, you can surely get a good MBA college and once you enroll in it, you can expect a good package minimum of 12 LPA.
Best of luck.
