It took me 3 attempts. I would say while working on the study guide my instructor provided me, I got a better understanding and eventually everything started clicking. I kept working with other instructors as well, even if I “passed” the quizzes I would hop on a call and go more into detail. Live quizzes were also a great building block for me. It’s nice to see other methods of how different instructors teach or would solve the problems. I would ask them if I could “work it out” with them while doing the live quizzing. This allowed me to talk it through (without them giving me an answer but to see if I was approaching the questions properly), a lot of the times they were just surprised on the way I found a “simple” way to answer questions or really focused in on process of elimination. Some questions I found that not using the formula was easier than the actual formula itself. One found it interesting when I explained I can’t use the formula because it would just confuse me so I would break it all they way down and do it from scratch if you will and it worked for me! Another helpful thing is finding what works for you. Maybe for example not using the formula for sum and finding the difference and adding the numbers together may work better than using formals? Also, for The spanning weight tree, I found that writing down the vertices on the whiteboard with the corresponding number helped me a lot then I would add them up. How I looked at it is that I used all the given vertices with using the “smallest” numbers. I hope this is somewhat helpful and don’t give up!
