Note for instructors and TAs

This page records substantive changes to the UBC edition of the BIOL 300 R labs. The purpose is to help BIOL 300 instructors and TAs identify any meaningful changes to the tutorials. The date in the footer reflects the most recent substantive update. Minor changes such as typo fixes, formatting adjustments, or changes that do not really affect answers may not require answer-key updates. Check with Vikram if unsure.
