<p>There is huge variations between the quality of a Calculus I course taken at different institutions:</p>
<p>First time- took it at Minnesota State University, ended up with a B, learned about 1/3 of what I learned the second time I took it.</p>
<p>Second time-took it at Iowa State- Finished with a C. the grading was way harder and the test questions were way more challenging but I learned about 3 times more than the first time I took it.</p>
