GRE

On a very realistic note, this is your last chance in CAT. I am saying this, because I did the same. Even I had 3.8 years of experience in IT with a mechanica degree. So, give it your best shot. If you are not able to clear CAT, then give GMAT, once you get 5 years work experience.

The best books for improving English:
- Wren & Martin Grammar
- Roget's Thesaurus
- increase vocabulary Rosenblum
- Norman Lewis books

You can prepare using good books-
Norman Lewis
Rosenblum
Roget's Thesaurus
Wren & Martin English Grammar
Also, solve previous years' papers.

You can aim above 310 to keep yourself in a good position. Above 315 is normally a very good score.

Yes, you can apply for all 2019 admissions depending on the deadlines of the universities, you want to be in. All the best.

There will be no cutoff score to get admit for that course at Georgia University. Georgia University will access your overall profile before giving you admit.

You should give entrance examinations for both. Both are very tough to crack, but they offer a really good package.
