Thank you all for the answers. I will go to integrated.
I never heard of those organizations to improve my marks, ill have a look at it.
The best desicion is to study in my city and have the chance of being an instructor, forgetting about the best academies like ctc or oaa (because i dont have that amount of cash). Of course the quality of those academies will be at a higher level but it's a lot of risk to do it there in my opinion. In my case at least i have the chance of being an instructor, and I will complement the learning myself with some CBT.
