Colleges in Uttar Pradesh

Sorry, I don't think that would be possible. I would suggest you to contact the college to know about the same.

I think it is pretty much late to get admitted for this session. But you can prepare now and appear for the next session by applying for different forms, which will be available from March 2019.

Please clarify what you want to know about civil engineering.

Specify the college you are looking for.

Dear friend, as per my knowledge student of class 12th wants to do the economics honours after his 12 then he must have economics as is a compulsory subject in his 12th. Some universities also ask for mathematics as one of the subjects.
Thank you!!

It would be difficult to find all entrance papers for free at one place.

As it is a UG course of 4 years, eligibility for this is that you have completed class 12th and after that you will get admission on the basis on FDDI rank, and it is totally a rank based procedure, as if you have given the exam, then you have to give the counselling fee by the 1st week of July to get your rank in the counselling rounds.

You are eligible but you have to clear exam then only you can do M.Sc in physics at IITs.

Dear friend, Getting a job to your dream company totally depends on your competencies, smartness and attitude. College can only assist you to get that, but you have to perform well at the final stage. As per my knowledge, the college assists you in terms of placements. But again, you have to grab those skills/abilities to achieve your dreams. Nothing will happen only by thinking but definitely will happen by doing so.
