The best people that you should be asking for advice are the people who are currently flying at any school at that given time .
Chances are that if they are happy then you too mite be .
Just dont base your decision on any particular persons or two people's view cause they might have got used to the bad conditions and might think its ok enough or then there might be the few who we call ' Champcha's ' if you know what I mean .
Go to the places , talk to the guys . Nothing much here . Face to face is real ..
Good luck ..
