You don't want your times to overlap. At my school, if you have a class time overlap, the system won't let you enroll in the course, and the only way you can do an overlap is by a petition that requires signatures from the department/s and professors signatures. So from the looks of what you wrote, no you cannot take the GEOG221 lab, if it runs the same time as the GEOG100 lecture. You would have to choose different lab time for 221.
