Kerala University was one among best in kerala. but not now.
the rules and the curriculum right now are very hard to crack I completed my BE under kerala university.
the worst case are the results. there is no certain time period in result publishing . it may come after one year or 6 months. and the worst case senario will be having an arrear if you get an arrear you would have missed 1-2 chances by then because the result arrives very late.
if you have a clear mind and the interest in taking up a course you may join here, but if you are under pressure of parents/peer make sure you think twice else it will be a hell of a ride.
