Hii Uday ..

Mention in which exam you got this rank.... here I'm assuming that you got this  in ecet exam (as you mentioned this in another question).

As you mention your rank in ESET is as 84 ..but to get the colleges like OU and J N T U H you have to rank below 50 ....

It is very hard to  get them for you with your rank .....but you can try in this following colleges with your score:-

• Sir C.R reddy college of engineering
• V.R Siddhartha engineering college
• PVP Siddhartha engineering college
• Andhra loyala institute of engineering and technology
• Pragati college of engineering
• ANITS, vizag
