I am assuming by droppers you mean people who left their degree at LPU in the middle. If so, then yes, there are students who do so because of various reasons.
One example of the same is my friend. She had joined B.Tech ECE in the same year that I did. But from the very first day she told me that she wasn’t interested in engineering. Moreover, hostel life was new to her, and made her overwhelmed.
She scored very poorly in Maths, in the December exams of first year. She got a Re-appear. In the next semester, she got sick for a month and scored very poorly in her mid semester exams.
Her parents were being updated regularly through the university’s official app. They got angry at my friend for not doing well academically. But when they reached the hostel a few days later and had a talk with her, they realized she wasn’t happy with her choice of stream.
They took her home with them. She did not attend the second semester exams, and eventually, she told me that she had gotten admission into some other course at some other college.
Currently she is happy with her decision to pursue fashion designing. Her story made me realize how important it is to make your choices with a calm mind, and not out of peer/family pressure.
