I would suggest everyone to attain some demo class then you realize the way of teaching... here trainer teach you in such a way that after getting job you can work with confident even experience guys doesn't know the reason of something... if they start some topic they will teach why this concept is required by SAP so that you will not forget particular concept... you can keep remember for ever without doing revision again and again... I attained SAP MM with HANA... and realize that this should be way of teaching... trainer teach to student with passion. They will clear your doubt. In logical way... so that you won't have any more doubt. Management is also good, They will try to resolve you problem as soon as possible
