So, I just found out I got a C on my last physics test. And I could have easily gotten an A, if I weren't a 'tard.
There were two major problems I did really, really poorly on. One was to solve for the kinetic energy of an object, one was a series of two-dimensional momentum problems.
On both of them, I solved for the velocity (which was a necessary step) but neglected to take it any further. I =
In my defense, though, I was 25 minutes late because I failed to wake up for my alarm, so I was kind of rushed.
Edit: and did I mention I'm likely to get a D in this class due to similar stupidity on previous tests and a failure to remember to do the online coursework? Yeah, I may have to repeat it. Hear that whoosh? That's my chances of med school flying quickly away.
The key to avoiding those dumb mistakes it to ALWAYS do a unit analysis.
