course conflict

Hi, I'm a second year biochem student who's aiming for dental school. I need to take kin 2y03/2yy3 or bio 2a03/3uu3 for the physiology prereq, but they interfere with the BIOCHEM 2L06 B lab sections.

The only 2L06B section that doesn't interfere with them is scheduled at the same time as the only CHEM 2OB3 tutorial... what do I do?
