You don't need a MAT score, you need to take SRMCAT and have a score of +65% in all qualifying exams.

No, it won't affect. You can appear for CAT 2018. Admissions will start from 2019, by the time your graduation will get over.

For NEET, be thorough with the syllabus of 11th and 12th NCERT. You also need to have a practice of solving MCQs.
However, for 12th, you need to go through your previous year papers and prepare accordingly.

Hi,
The basic principles you should keep in mind before preparing for GMAT/GRE are:
1. You must create a realistic schedule of daily study. You should at least study for 20-30 minutes every day.
2. Use only official study material and only refer official books published for any of these exams.
3. Learn

You should have scored nearly 200 and above. So you can get good IITs and NITs. If you are an OBC candidate then your rank will be depended on that year's JEE Mains exam and cut off.

Hi,
Yes, it has very good chances. Bangalore and Hyderabad have good chances for scores below 200, although for Mumbai you may not be able to qualify.
Keep hoping for the best.

Some colleges of IP University take admission through AIEEE ranking. In the university only 15% seats are reserved for outsider’s means for them who pass their 12th from outside Delhi.

MDI-Gurgaon, Christ-Bangalore, KJ Somaiaya-Mumbai are some of the top colleges offering state of art placements and you have a fair chance to get admission at this score.
