Blocks are 3.5 weeks long during the school year, and 3 weeks long during the summer session. The Block Plan offers complete immersion in one subject for both students and professors: during each block, students take, and professors teach, just one class.
This nine-week online course created by OFC’s Keith Berman is for sophomores and juniors who are looking for a rigorous overview of the college admissions process, but not necessarily individual counseling. Enrollment is limited: http://cty.jhu.edu/family/OFC.html
