for doing post graduation (engineering) in uk what exams do i have to give?

Applications are made on an IELTS Application Form which you can send or take into a test centre, along with the test fee, two passport sized photographs, and a photocopy of your passport/national identity card. You will also need to include your passport number, or in some circumstances a national

First you have to clear IELTS for language after which you can get visa for that and any kind of engineering you can do over there but in my concern IT is better in all options.
