I just went over my math cumulative corrections and I realize how many careless mistakes I made. GEEEZ I'm so stupid. ! I could have got a better mark. I combine the like terms wrong, forgot to make the slope perpendicular (so the rest of the question was wrong) and divided wrong, like wth. Some of the questions were so simple and I had no idea what I was doing. It was so simple. My brain wasn't working well that day. "sigh" Next time whether if its a cumulative exam or test even a quiz I need to calm down and think outside the box.
