Which is more convenient to reach to college in Trivandrum from the house (Varkala,take 1hour 30minutes by train )or hostel in tvpm?
If you are a regular student who will need to travel 5-6 days a week for college, then I suggest you take the nearest hostel in Trivandrum because travelling daily through train can be a hassle. You will be wasting 3 hours per day in travelling which you could devote on studying or taking rest. But, if you think you won't be very regular, then there is no problem with train travel.
