Second semester is particularly more “wonderful” because students started paying less attention. 1L students now know their place in the pecking order of law school’s intellectual food pyramid; 2L are ready to become 3L; and 3L are ready to leave school, if they had not already done so.
This means that students generally didn’t focus on studying as much as they had the first semester, making this time of the year the most “wonderful.”
That said, everyone will suddenly become expert on the class 48 hours before their final starts. Magic will happen!
