    I’m voting to close this question because it is not a legal question. LSAT is specifically designed to not contain any actual legal questions, but to test aptitudes in logical reasoning.

Option C is wrong because it excludes the possibility that most students might have received exactly a B minus.

The question permits dividing the group in two subsets. One is {students | grade < B_minus} and the other is its complement {students | grade >= B_minus}.

Option C is in terms of the set {students | grade > B_minus} whereas option E is in terms of the set {students | grade >= B_minus}. Only the latter matches the description.

  1. Most (equivalent to "more than half") of the students, attended every session.
  2. All students who received a score below B- (that is, C or lower), missed at least one session.
  3. Given (1) and (2), more than half of the students received a score of B- or better (better than C).

The difference is "higher than B minus" vs "B minus or higher". A student who received exactly a B minus is included in the latter group, but not the former. "More than half" and "most" are exactly equivalent, at least in this case.

However, this is a logic question, not a law question.
