No, it is not necessary. You can take direct admission also.

Just focus on your studies from 2nd year, and after 3rd year you can join coaching for GATE preparation, specially focus on discrete maths, data structures and computer organization and architectures. (COA). And, perform well in GATE.

If you are from UP, then there is no state rank for you. State rank is given to those students who are from outside up and appeared in UPSEE examination. (you will get only your category/subcategory rank).

IET Lucknow is much better college than upes Dehradun. Here, you will find best infrastructure, placements as well as academics. IET Lucknow comes under top 100 reputed government colleges if India.

If you are getting IET or KNIT, then don't go for Jabalpur, if you can't get any of them, then you can think for Jabalpur Engineering College.

1. IET Lucknow (government)
2. BIET Jhansi (Government)
3. KNIT Sultanpur (Government)
4. JSS Academy of Technical Education Noida (private). It's hard to write all. Please go through this link:
