Assistants test your understanding of the notions involved in the labs. For example, they might ask you to reason about what happens if some simple modifications are introduced to the code.

• Before you demo, you need to send your code by email to your assistant. This only involves the files you have modified (typically .c or .h files). Only after you send the code by email, will you be able to demonstrate.
• The assistant might remove comments from your solutions to check your understanding of the code your wrote.
• During the demo of the sent code, the assistant will ask you to reason about the code. The assistant might test your understanding of the lab descriptions, ask questions about the meaning of steps in your code and about the effects of some simple modifications.
• Observe it is not enough to show code to which you have produced explanations as comments.
