KCUMB:
Typically ~ 8-12 lectures Monday, and Wednesday-Friday
Tudesday OMT ~ 8-12 (usually just half of that, either 8-10 or 10-12)
Afternoons (~ 1-5) are labs... anatomy, micro, path, small group discussions, etc.
Friday afternoons are usually free after noon or so, sometimes later if it is a packed week. One other afternoon during the week is often free, but not always as some weeks are pretty busy. At the worst you usually only have one or two days a week where the afternoon is completely full, with the other lab afternoons requiring your attendance for an hour or two block (could be 1-3, or 2-3, or 3-5 etc.).
