Hello

It would be difficult to tell you about the expected cutoff as it varies every year from college to college depending on various factors such as the difficulty level of the exam, number of candidate appearing in the exam, number of seats, etc.
You can go through the link below and check the previous year BCECE cutoff for reference and to have an idea about the rank required to get a seat-

Good Luck!
