Hi Sophia,
Thank you for reaching out!
The annotated notes for BioBiochem have been posted in Key Documents on Student Portal.
If you refer to the BioBiochem class structure, which can be found in your Prep101 BioBiochem Classroom Companion (also posted in Key Documents), you'll see a breakdown of the lessons covered in each class.
Lessons 1.1 to 2.6 are covered within the 9 BioBiochem classes and all of this is available on the Student Portal.
I think the confusion stems from the before-class readings because it covers Lectures 1 through 6 and you may be looking for these lectures as opposed to the corresponding lessons for each class.
Let me know if this clarifies things for you!
