Hello Rahul, It's very nice to hear from you that you are interested in doing one year Diploma courses for which qualification is either 12th or graduation. I must congratulate you for thinking on these lines. One must keep on enhancing one's qualification every year. I will advise you that please download brochure cum application form of IGNOU. This university offers a very wide variety of courses. Select the one that you like. Best wishes.

For all the information regarding admission procedure, just follow the link.

You can crack GATE civil exam and by obtaining good marks in the same, you can take a college after the counselling of B.Tech.

Hi, last year the cutoff was ranging between 95-97. It would be difficult to predict anything but it would be either equal or probably higher.
All the best!

There are lots of colleges in Noida and Ghaziabad. No one can provide you the list of all the colleges.

For getting admission in Amritha University you need to appear for AEEE. With you JEE score and 12th score I can surely assure you that you can easily get EEE branch in SASTRA.
