Ghaziabad

In terms of placements and studies the best college is the JSS Noida as this college is the best private college in whole UP and also this college has the best study curriculum then any other college in ghaziabad.

In terms of average package and highest package offered, AKGEC has the highest package of Rs. 35 Lacs and the average package stands at Rs. 5.5-6.8 Lacs.

The chances are quite low but it is not sure as according to the last year the general rank of the OBC students accepted by this college is 9k, it is sure that there will be slight increase in the closing rank but not confirm.

Hi Shivangi,
It is advisable to get in touch with the college officials for detailed information as admission process varies for every college.
Thanks.

Yes. It is possible. If it was a deemed university or an autonomous college, it is clear. Else, in case of having an affiliation, both the colleges must be under same university affiliation.
You must avail a TC from your current college to join the other. You may need to compensate your current college mostly happens if you belong to any of the deemed universities.
but for that you need to have very good first year pointer(above 9 preferably) without any backlogs. Then, you need to contact your college exam section to know further procedures.
Hope this helps you.
Be free to share any problem you have.
Good luck. :)
