Welcome to the RHSA SBI4U grade 12 Biology Google site. Check here if you are absent, have lost a worksheet or forgot the homework. You are welcome to print the lecture notes and bring them to class. However, the lecture notes alone are a poor substitute for attendance and participation in the class. Learning happens when we work together.  All assignments are due at the beginning of class otherwise late marks will be deducted.

Important Updates for the 2023 school year:
