Hey Ajaz, ICET is accepted by many top B schools like IIM Vishakapatna ,ICFAI (IBS) Hyderabad ,IPE Hyderabad etc. first of all you should be mental prepared that there is no timings in MBA college since youhave to study and work hard -day and night for scoring good . Getting good grades in the college should be the prime motive for the student for getting a good package. Coming to attendance if you have some attendance issues I wouLd suggest you to opt for distance education .There you will get a lot of off time. 

Best wishes
