Withdrawn

I have made a big decision in the pass week.
I withdrawn one of my class. It was such a difficult decision to make. I was having so much stress about this, since this is my first withdraw I ever have and this is one of my major's elective class...
Yet, it is already a fact that I did withdraw.
There are couple reasons for me to withdraw this class.
First, I cannot handle it. I was taking five courses this semester and four of them involve projects. I have been spending all of my times on working on coding and meeting with my groups. I did not have any extra times to study the class.
Secondly, that course is way too advanced. I was having troubles understanding the materials. Perhaps I did not have a good enough background knowledge in that field.

Thirdly, I did not just want to pass the course. I want to actually learn it. Being honest, I was not doing bad for that class. I took the midterm and I do not think I did bad. Yet, I do not want to entitle myself of taken this course and actually did not fully understand the materials.
Ans plus others and others reasons, I withdrawn.
I feel some relieves after all.
I finally have some extra times this semester to work on something I like to do.
Hopefully, I would not regret my decision later on.
