With a score of 70 out of 500 in CUET 2025 and being from the general category, the chances of getting admission in BBAU for B.Com might be low because the cutoffs usually go higher for general category students. But still, it depends on the number of applicants, category wise distribution, and seats available that year. You can keep checking the official counselling rounds, and also apply for other backup options to stay on the safer side.
