Intro Bio Grades, Fall 2009:    Last updated: November 05, 2009 12:51 PM

Grades will be posted after each exam using the last 5 digits of your Columbia University Personal Identification Number (CU PID). This number is NOT your Social Security Number, it is (probably) not the number you wrote on your exam, and it is not even the number you find on your CU ID card. You can find your CU PID by logging in at the Registrar's Student Services Site and looking at your Personal Profile. This number is provided to instructors along with your name, etc. when we set up the spreadsheets for the class. The switch from using Social Security numbers was instituted as a safeguard of your privacy.  We, and perhaps other courses, will be using this number to identify your grades. So it is probably a good idea to get familiar with this number.

If an exam turns out to be more difficult than expected, grades will be adjusted upward: if the overall median grade in C2005 in a given exam is less than 73, the difference between the median and 73 will be added to all grades (in F2401 as well as C2005).  If median grade is greater than or equal to 73, no adjustments will be made -- if that happens, you just enjoy the bonus.

The mean final letter grade in this course is expected to be the same as in previous years, a low B.

For exam 1, an adjustment of +4 was made to all score, and the score listed reflects that addition. The score written on the physical exam copy will be 4 points less.

Grading Guidelines for the year 2009

Students will be guaranteed the grade shown if they achieve the indicated final score.

Final grades will be calculated on the basis of all four exams but after dropping the lowest of the first 3 exams.
If you achieve the indicated score or you are guaranteed the corresponding letter grade. The scale may be adjusted downward slightly, but will not be adjusted upward. That is, points required to earn a particular grade may be decreased, but will not be increased. However, the scale is intended to be realistic, and no major adjustments are likely. A+, D and F grades are given on a case-by-case basis.

C2005 (includes up to 60 points from quizzes) F2401 (no quiz points; same as C2005 number - 60)
