*** FINAL EXAM WILL NOT BE IN PSYCH 1924 ***
- Final exam will take place in Broida Hall (BRDA 1640), 8am - 10am on Wednesday 3/20

Format of the exam
- Similar to midterms, but designed to take two hours (~twice as long)
- Mix of questions
	- Short answer
	- Briefly describe / define /state…
	- Write code
	- Fill in the blank / complete the table (or diagram)
	- True / False, if false explain why
	- Given code, what is the ouput

Topics
- Will cover everything from the start of the quarter up to Tuesday (3/11) lecture on Threads.
- Covers lecture, labs, homework, and reading
	- Use lecture notes as breadth of topics, and all other course material (lecture, hw, labs, reading) as depth.
