Guys !! 20 july 2014, when FYUP was scrapped so that Now we are the unique batch, jinke na aage koi hai aur na peeche.. Bt ye jo hai iski bhi koi market value nhi hai... Bcoz it is not A.I.C.T.E Approved.. Now the time has come and the deadlines are set u.e we have to take the A.I.C.T.E approval upto 20th feb and the clg principals are not supporting us.. Just faculty are supporting us jinke hath mai kuch nhi hai.. So we have made the union of students and we had spread our arms in 17 colleges and they are supporting us.. And how you can support make the videos, write the text, make the trailers for appeal of A.I.C.T.E. Approval.. All these things must have venue of protest, date and timings.. And they are as vishwavidhyalaya metro station on monday 9th feb @ 9:00 am sharply.. Reach there in the huge amount.. Bcoz we all have to take the initiative...

Our group is the best one because we play together ,eat together,dance together and beat the birthday boy for the celebration ...................
we plan for the next day for the happiness not for the study ...
we fight together for the no reason and again shake each other hand for the best reason that is friendship ........that is happiness .....
that is to take every next breath with together on the cost of unity.
