regressive education?

I have realized that something is amiss in my eduction.  Let me illustrate.

MATH

I took calculus my sophomore year of high school.  Our school did not have AP calculus, so I had to take college single variable again (basically review of high school calculus) first semester of my junior year.  Second semester I took differential equations and linear algebra 1.  Senior year of high school I took multivariable calculus and differential equations and linear algebra 2.  At college, I got credit for multi and single variable calculus as well as linear algebra, but not for differential equations, so I took differential equations a third time.  Second semester last year I took analysis.  First semester this year I took probability and statistics.  Now, for the first time, after seven college math classes, I am not in math.  

But...

I can barely add.  I fear multiplying things in my head.  I feel so slow all the time that 2+2 often doesn't equal 4 but rather some enigmatic, vaporous concept hovering beyond my grasp.  I wish I could tell kids that no matter how much math they take, they will always make the most mistakes on adding and multiplying and subtracting and dividing.  Integrate with a trig function?  Sure.  Solve a partial differential equation?  On a good day.  But add?  No way.

BIOLOGY

I took two years of biology in high school and did AP bio out of school on my own.  In college I have taken biology, neuroscience, and systems neuroscience.  Still, if you asked me the equation of photosynthesis, I would look at you blankly.  I can tell you the details of your visual pathway, but ask me exactly what a peroxisome does and I probably can't remember, even though I drew pictures of the things in seventh grade.

CHEMISTRY

I took two years of chemistry in high school.  In college I took solid state chemistry, organic chemistry, and I'm now in biochemistry.  Yet I still have trouble grasping titration curves and molar calculations.  I can tell you the catalytic triad in enzymes but I can't tell you what exactly is in a atomic mass versus an atomic number, or how to calculate atomic weight.

I won't go into physics because that is something relatively new to me.  The actual study of it anyway.

My point is, though, that even though I am at one of if not the most prestigious and accomplished math and science schools in the country and the world, I have no idea how to add, I can't remember what exactly is in a cell, and I can't calculate molality.  It's like I keep trying to shove complicated information in my brain, but out the other end the simple stuff keeps dripping.

I think our education system needs to pound in the fundamentals even more.  The greatest mistake we college students make is losing a negative or adding something wrong in a 20 step problem.   There's something a little crazy about it, like we're still in elementary school.
