Here are a lot of ratings and rankings out there - some paid, some truthful, some very close to accurate and some outright outrageous. This is my ranking for B-schools according to my experience with CAT for the past two years. IIM, Ahmedabad (PGP only)IIM, Bangalore. IIM, Calcutta. FMS, Delhi (Ranked better due to excellent ROI)XLRI, Jamshedpur (Ranked 1st for HR in Asia) and IIM, Lucknow (PGP only). IIM, Kozhikode = MDI, Gurgaon = SPJIMR, Mumbai (one can argue this to be in the same league as XLRI and IIM-L for applicants with experience; but at the same time disadvantageous if you are not clear about your specialisation) IIFT Delhi (+1 for trade). NITIE, Mumbai (1st for Operations) = SJMSOM, Mumbai (IIT B) =IIM, Indore (Huge Batch Size, Huge weightage to 10th/12th marks) = JBIMS (Maharashtra Only Preference Pushes this down the list)IIM Shillong (Locational Disadvantage) = NMIMS, Mumbai (Locational Advantage, but high Fees) = SIBM IIFT Kolkata. TISS, Mumbai ( only HR is taught) = IIM, Ranchi (for only PGP). IIM, Trichy (slightly better than IIM U, Rohtak ; slightly below IIM, Ranchi) = IIM, Udaipur = IIM, Rohtak = Dorms (IIT Delhi), Delhi.

There are a lot of benefits of having a Ph.D:
a) You can indulge in the luxury of having Dr as your title. B) You'll learn how to be tough (mentally tough that is) from all the grilling, criticizing, and second guessing you will have to endure when you present your research proposal. C) Your analytical skills will sky rocket. This really depends on the type of Ph.D. you pursue, but it is a given that you will learn to sharpen your analytical skills, and will then be able to apply these skills to subsequent ventures. D) It is the highest possible degree that you can achieve. If you strive for greatness, and nothing short of being the best will do, a Ph.D. will definitely fulfill your intellectual satisfaction. E) You will be a recognised expert in your field, and you will have a piece of paper to prove it. Who knows, you may even be lucky enough to win a Nobel Prize one day!
f) Some jobs actually require you to have a Ph.D. or equivalent.
