Astronomy 101EA: Stars, Galaxies, Cosmology

MW 7:00--8:15 pm

Instructor: Dr. David Jeffery

The students's marks, averages per mark category, cumulative average, and preliminary letter grade are shown below followed by some explanatory tables. The students are listed in extended alphabetic order by their aliases. Only students with aliases are listed.

Drops: A dropped mark is the negative of actual value, except that ordinary dropped 0's are listed as -201 and special drops are -202. Temporary drops for items that must be completed are -301.

Tables: There are two explanatory tables at the bottom of this file.

Table 1: This table shows the category of the markable items in the 1st column, the weighting of the category in the 2nd column, the number of drops allowed for the category in the 3rd column, the total number of items in the category in the 4th column, and the maximum mark for each item in the category in the 5th column. All the items of a given category have the same weight regardless of maximum mark.

Table 2: This table shows the class average, class standard deviation, and class mean GPA.

Grade Calculation: For preliminary grades, the grading scheme is:

Grade Lower Bound for Grade on Cumulative Average A 90. B 80. C 70. D 60. F 0.

Alternate grade schemes Grade Scheme -1 0. 57. 60. 64. 67. 70. 74. 77. 80. 84. 87. 90. Grade Scheme -1 0. 40. 50. 55. 60. 65. 70. 75. 79. 83. 86. 89. Grade Scheme -1 0. 35. 49. 55. 60. 65. 70. 75. 79. 83. 86. 89. Grade Scheme -1 0. 60. 60.0001 69.9999 70. 70.0001 79.9999 80. 80.00001 89. Grade Scheme -1 0 59.9998 59.9999 69.9997 69.9998 69.9999 79.9997 79.9998 79. Grade Scheme -1 0 54.9998 54.9999 64.9997 64.9998 64.9999 77.9997 77.9998 77.

Your cumulative average is the weighted average of the averages of each mark category.

At the end of the course, I use these preliminary grades as a ***GUIDE*** in fixing the final grades. Emphasis on guide. I will make the final call.
