I am quite pathetic when trying to solve problems. When solving problems i always refer back to solved examples. It's like comparing my self to someone who can trace a picture very well but can't draw the picture. The examples only help so far, once a much harder problem comes I'm finished. I have no idea how to begin. I've noticed this in physics, math, and comp sci. But, i do well in these classes, but my inability to think is very stressful. Any suggestions?
