Your Diploma cannot get you admission in abroad universities, so try to complete your B.Tech, then try for abroad studies.
All the best.

Hi,
Some of the popular books for IELTS preparation include:

There is no such best book as what is best for me might not be best for you. These are generally the most followed books by test takers.

If you apply in USA universities, then you have to appear for GRE with TOEFL. For other countries, you don't need to appear for GRE, only TOEFL or IELTS is enough. But if, your academic record is not up to the mark, your GRE marks help you to get admission there.
For MBA admission you need to appear for GMAT with TOEFL or IELTS as GMAT is must for MBA in abroad.
All the best.

Unfortunately you are not eligible for Canadian Universities because of your academic score. You can try for SPP colleges of Canada where you might be eligible to get admission. For that, you need to score over 6.5 band in IELTS and at least 300 in GRE. Besides, GRE and IELTS are totally different exams, so you have to appear for both of them. All the best.
