I just finished uploading updated video solutions for the Fall 2019 MAS-I Exam, problems, #12, #13, #15, #20, #21, #23, #31, #33, and #44. Each of these now has a spreadsheet solution as well as a calculator solution.
I also went through all of the Fall 2019 exam and made up a sample of what my Spreadsheet Scratchpad might have looked like at the end of that exam, using the spreadsheet to calculate nearly everything and hardly picking up my calculator at all. This is included next to the pdf solutions for this exam in the Sample exams tab.
From here on out, I’m going to work on producing as many additional video solutions for practice problems as I can leading up to exam day. Feel free to let me know about any specific problem that you’d like me to prioritize on the list for getting the video solution completed.
