The correct way to determine your current numerical grade (right now) is to convert your score on Exam 1 and the four quizzes into percentages and apply the weighting: Take your quizzes and compute the average (e.g. say it is 3.25), divide that number by 4 and then multiply by 100% (e.g. 3.25/4 x 100% = 81.25%). Next, take Exam 1 raw score and divide by 65 and then multiply by 100%. Now we must apply the weighting. In the end, exams will be 75% or your score and quizzes will be 25%. So we need to apply this weighting. Take your quiz percentage (e.g, 81.25) and multiply by 0.25. Then take your Exam 1 percentage score and multiply by 0.75. Add those two results and that is your current numerical score in the class (with the correct weighting). For a score from 90 to 100, that is an A, and the 80 to 89 is the B range and so on. If you want to get technical, A- is 90 to 93, B+ is 87 to 89, and so on. Now if you want to get super technical, I have an undisclosed big curve for the C range, a moderate curve for the B range, and a very tiny little curve for the A range. Thus what you compute, is actually the "worst case" scenario for your grade.
Scores have been posted on Canvas. Average was 49 out of 65 (75%).

Many thanks to Ryan Bertram (Astro A100 student), who introduced me to this neat YouTube video (courtesy of Rob Bryanton, Canadian author) that discusses the ten possible dimensions of our universe.
Many thanks to Tim McCormick (Astro A100 student), who introduced me to this fantistic webpage that models early solar system formation.
Many thanks to Elizabeth Potter (Astro A105 student), who showed me this neat webpage highlighting the relative sizes from the Local Group down to Quarks (and the corresponding orders of magnitude, or powers of ten)
