I joined in datapro classes for learning java during holidays before getting married. They conduct the classes for bunch of students in some kind of seminar hall.They taught every thing with the help of projector so we catch every thing while they teach.
They had arranged mikes at the corner of the hall so their is no problem for the audio.Some lecturers are really taught very well, they explain every point pin to pin.
The java class duration is 45 days and the fee is 5, 000/-I learned only core java from here.
Some lecturers are very well in teaching but they cannot concentrate on students, they only concentrate on completing the syllabus with that period.
But believe me they really provide every good material for us.Its really worth the cost.They will some times ask about reviews of the class, if it is possible then they will change the faculty also.
But the problem here is we cannot ask the problem directly and they dont have that much time to clarify our doubts.If we have small doubt then they will clarify in class other wise we have to mail our doubt then they will give you clarification about it.
It is some what okay coaching class.
They will offer many courses like hadoop, oracle, cloud computing, html everything what ever you want.
