# Study Modules

The “Slides with commentary” is the most complete representation of the material you are to learn in CS135.

The slides portion of those pages are also available as 1up and 3up PDFs. They work better with screen readers and print better, but lack the commentary, videos, and self-check exercises.

### Errors

Errors in the lecture slides will be listed here. If you discover an error that is not posted here, please talk to your instructor about it.

• 2021-09-10: While not an “error”, we did provide a bit more guidance on the term “translate” on slide M01-23 .
• 2021-09-20: Reformatted contracts on slide 17 and the exercise that follows to match current style guidelines.
• 2021-10-04: Clarified M06-47 that the data definition for ne-listof is not required in assignments.
