This attitude is absolutely a nail in the coffin for your future success in college. Almost every single student who enters a college class with this goal fails miserably.
I do not blame students for feeling frustrated when they feel they are being forced to enroll in a course that seems equivalent to one they took in high school; however, there is a large distinction between courses titled "algebra" in high school versus those titled "algebra" in college (or, at least, there should be).
It is a sad reality that the material in a college-level math course (or any college-level course, for that matter) is covered at a pace that is two to three times faster than in high school - this is not your professor's choice. We are contractually required to cover certain core material and, for one reason or another, some courses just have too many topics with too little time. Trust me when I say that I would absolutely love to cover a course at a pace that allows for thoughtful exploration and slower development. The discussion of how this could be achieved is beyond the scope of this blog post; however, it is something that your professors are well-aware of.
I find it difficult to not come back with a witty quip about the fact that "your mother probably didn't show you how to tie that exact pair of laces on that exact pair of shoes either, but somehow you figured it out." The fact is, it would be impossible, and educationally unsound, to do every example in the world for you - we have to see that you can think for yourself.
