Which testing training center should I choose in Hanoi?

In the age of information technology, testing has become an indispensable hot job at software companies with continuous recruitment waves. Therefore, tester courses in Hanoi are also sought by many people to supplement their professional knowledge and skills.

From friends who have studied testing courses from testing training centers, I know three centers that are Testerpro, Daotaotester and IT Max. Anyone who has attended the above centers can tell me which courses are good?
