Mero college experience bata degree dheraii important cha. Malai pani dheraii garo bhathyo for the first time in my life as I depend on myself to study. What I did was I always try to finish all the assignments as it almost covers 40-60% of grade and you learn a lot too by doing assignment. So you don't have to worry much about messing your exam unless you want grade 'A'. And it also depend on college. I completed my undergrad where most of the classes were held in the evening and weekend only and the courses were structured for adult people- most of them were full time professional people. So it was not like old school style classes. I did pretty good on my undergrad degree. Most of those professional adult people came to college to get a promotion on their job even though they have tons of years of job experience because of not having educational degree. At the end, it depends on you how much effort and sacrifice you can give to achieve your educational career. If you have made up your mind then pretty soon you will figure it out your own way to study. Once you figure it out, then you won't be an Average Student. You will be like-"Can do attitude person". So, wish you all the best and find colleges accordingly.
As @rockey07 bro has mentioned - "pain is temporary but if you quit it lasts forever".
