On monday I'll write the test and I'm a bit afraid. I finally understood how to factor a quadratic equation. But I just try different values, the diamond-method makes it more complicated for me. I can find the vertex and the x-interceptions of a quadratic with the formulas. Completing the square nah, I guess I just have to memorize the procedure.. Fencing and "ball-throwing" problems are ok. They are a bit like physics.
