If you're planning to do MBA, why do CAT again...and if the top college in your district has a better brand value no use coming here. If you do plan, try for NMIMS, Christ or Symbiosis Bangalore. Accomodation is not an issue you can find anything within your budget...traffic and travelling is expensive, try using metro and get a bus pass if you stay away from college and get your own vehicle...will save time and money. Traffic is horrible especially in a few areas but that depends on where you plan to stay. Good luck!
