**me**, Tuesday, May 29, 2012 at 12:46pmThere are 2 halves in the course:

1st half has 120 points

2nd half has 140 points

-- for a grand total of 260 points

If a student earns 81% of the points in the 1st half, she earns 0.81 * 120 points

-- 0.81 * 120 = 97.2 points

If there are 260 total points in the class, and the student wants to earn a B final grade, that is 0.8 * 260 points

-- 0.8 * 260 = 208 points

208 - 97.2 = 110.8 points

-- the student still needs 110.8 or 111 points from the second half
