I know a friend of mine who had studied in both excellence and executrain. he said that excellence is much better than executrain. mainly because of the more personalized care and attention by the tutors. they find time for the students no matter what and are ready to support the students even through phone calls and mails.
the tutors are not normally on time in executrain. and their course schedules are never kept on time. and no revision classes are conducted as per their schedule.
