Engineering is tough.
Our class was composed of 50 students.
I remember, after the first term, half of the students in my class failed algebra and trigonometry.
After the second term, only 10 of us managed to stay regular students (mostly due to engcal1).
And after the first year, only 6 of us survived as regular students.
After four years in the program, only 4 of us managed to graduate as regular students.
It's tought, but it's doable. You just need to study hard and study smart.
