Suggest me best college of AKTU for chem engg. Which i can get at the gn rank of 35027??

Based  on your rank  you are not supposed to  get a government College in chemical engineering. You can get a private Colleges if you want to take admission in these Colleges. The Colleges where you can take admission are:
1. Noida Institute of Engineering and Technology
2. Lovely Professional University
3. Shiv Nadar University Greater Noida.
These are the private Colleges where you can get admission in chemical engineering. There are few Colleges of UPTU having chemical engineering. So you have to struggle more. It also depends on the cutoff list. The cutoff list vary from year to year. It also depends on the number of students appeared in the exam and the level of paper whether it is easy , moderate or difficult. You can come to know about different Colleges by visiting their respective websites. You can even predict your college according to your rank. As you are in general category you are not getting any extra advantage. As your general rank is not so good so you cannot able to get a college.
You can even dropped this year if you want to get a good College.  And you can do preparation for the UPTU exam this year and attempt it next year. So you can get good rank and able to get College of your choice. Otherwise you have to do your counselling properly. Give your preference in the first round of counselling and further give the name of the Colleges based upon your rank. So that you can get a college.
