<p>Another thing is…and I know some of you engineering/science/math majors can attest is that different folks can grasp different concepts at quicker/better level. Yes, there are some students who went A+ right through Calculus I, II, III, Linear Algebra and Differential Equations BUT there are many cases where one found Calc II easier than Calc I or Calc III easier than Calc II. Some are great at ordinary Diff Eqs but struggle a little with partial Diff Eqs (and vice versa).</p>
<p>Even on the jobfront, me (and other database/DBA types) cannot believe how some hot-shot Java/C++/Whatever developers cannot grasp database concepts (foreign keys, etc) but can create an abstract data type from another abstract data type can reduce the lines of code by 50%.</p>
<p>It’s what makes engineering and science exciting because so many folks can specialize/struggle in so many areas.</p>
