Even though SENA is a public institution that is free, I think they offer very complete programs, of great quality and with very experienced teachers. In their programs, they don’t only offer a complete theoretical studies in which one can have all the necessary theory, but they also offer a mandatory practice where students can put in practice in a real life context all the theory learned before.
I consider my program to be very useful and complete. And they also have fixed classes schedules so If a person can only study in the morning, then it’s possible to enroll in that hour frame.
