You can estimate your course grade in CMSC-202 by doing this:

1.  Gather (or create) the following data:
   a) the grade you expect to get for each homework.
   b) the grade you expect to get for each exam.
   c) the number of discussion sections you expect to miss.

2.  Compute components of your grade

   a)  Compute H, the contribution of homeworks to your grade:
         throw out the lowest homework;
         average the rest;
         multiply that average by 0.4;
         assign that value to H

   b)  Compute E, the contribution of exams to your grade:
         average the exams;
         replace the lowest exam with that average;
         compute the average again;
         multiply that average by 0.6;
         assign the value to E
         
    c) Compute D, the contribution of section attendance to your grade:
         if you have missed fewer than 4 sections,  D = 5
         else  D = 0

3.  Compute your grade

         Grade = H + E + D

    If Grade is 90 or more   A
                80 or more   B
                70 or more   C
          below 70  D
