Hi Jay

Will suggest you to keep tracking the official website of BCECE to know the joining date. The authorities of BCECE will release a notification regarding the same, else, you can contact the concerned authorities of the college where you have been allotted a seat. 

All the best! 

your restlt had been declared on 19 june 2018 and your councelling had also been done in which you had selected your college and also had submitted your documents . if you have done these things then you have to finalise your college by giving the fees at the time they will tell you the starting date of college even you will also  get th email from the college on your registered ID.
