MBA Entrance Exam

It is more than enough. U just need to give 6 hours a day. Just follow the following steps.
DILR
Do as many DI-LR sets for practice. Do solve all the questions from CAT 2001 to CAT 2008. The more you expose yourself to different types of DI and LR, the better it would be. Apart from the CAT papers, solve the questions from your prep material.
VRC
There are two types of VRC questions:
1. Those that are based on knowledge - Grammar & Vocabulary based questions
2. Those that are based onunderstanding of paragraph(s) and logic- Reading Comprehension, Para Jumbled, Para Completion, Para Summary, Critical Reasoning
Of the above two, the latter is something that you must get a strong hold of. Since it is not based on prior knowledge, practice can help you score high. Focus on accuracy.
Quant
This is probably the tricky part. I would suggest that you ensure that you know how to solve almost all of Level 1 questions. That would mean that you must have the basics of all areas in place. Then, look at doing depth in a couple of areas. If I look at the past CATs, Number Theory & Algebra dominates the CAT. There is a bit of risk attached to picking & choosing Quant topics.
In any case, use your Mocks as a strong prep tool. Analyse each Mock thoroughly and let mock tell you what areas you need to work on.
ALL THE BEST!

You must know the difference between,
MS Ramaiah and RIMS (Ramaiah institute of Management studies)
MS Ramaiah is a very good college with good placement, faculty, exposure, extracurricular facilities.
On the other hand, Ramaiah Institute of Management studies (RIMS), Ramaiah Institute of Business School (RIBS) and Ramaiah Institute of Legal studis (RILS) are under one director, which is completely different from the MS Ramaiah.
People gets confused and joins RIMS RIBS or RILS thinking that it's the same as MS RAMAIAH, but it's far from it. They just run an institution with the same brand name to fool people.
They are very money minded and sexism is seen everywhere in the college.
Some of the most useless and annoying things about this college is (RIMS, RIBS AND RILS)
1. 90% attendance is compulsory, if you fail to meet this attendance in any subject, they will take a huge fine about Rs. 10000 per subject for MBA students, and for under graduate it's lower than that. But, two years back, I heard that someone had to pay fine of Rs.18000 for one semester.
2. Uniform covers 90% of the body and is made up of pure synthetic, which is very uncomfortable.
3. There is no sports ground. Very poor infrastructure and no extracurricular activities.
4. If any students is seen using phone anywhere in the college building, then their phone is confiscated.
5. Even if you are 2 mins late, you will not be allowed inside the class.
6. There is no festive holiday for anyone.
Not even on Janmashthami or Baker-eid or anything.
7. Management is very poor.
But, MS Ramaiah is a very good and reputed college and they do not have con like RIMS.
