My son goes to a school that had block scheduling last year but dropped it this year. Nobody wanted to drop it except the school board. Teachers, students and parents loved it.
Now we have 7 regular periods a day.
Before there were 4 classes for half the year and 4 classes the second half the year.
Advanced math students could get in tons of math classes by taking a math every semester until they ran out of classes. Foreign Lang students could take Spanish 1-3 and have time for both AP Language and AP Lit. Many student entered specific programs (like a medical program or an avionics program) and arts students had plenty of time for plenty of arts classes (you get 4 extra classes over your time at high school with the 4x4 schedule).
They had provisions for those taking AP classes so they were ready in May. I think it depended on the particular AP...I am not exactly sure how it worked because we were switched to the 7 period day.
