Congratulations if you have studied A-level Chemistry or any level in equivalence in high school! Cause the first two sections of BCM largely contain information about Chemistry. If you didn’t learn A-level Chemistry, that’s fine! (It’s not the end of the world!) The part of Chemistry involved in Biology is not that much. (Frankly you only need to know elements like C, O, H. N from the periodic table!)
For the first section, Chemistry of biomolecules, instead of going through the PPT in lectures, pre-recorded lecture videos are provided to watch and learn in your own time. You will need to answer questions in lectures.
