+
+---- DATA STRUCTURES ----
+
+>> A1: (2 marks) 
+>> Copy here the declaration of each new or changed `struct' or `struct' member,
+>> global or static variable, `typedef', or enumeration. 
+>> Identify the purpose of each in roughly 25 words.
+
+---- ALGORITHMS ----
+
+>> A2: (2 marks)
+>> Briefly describe what happens in a call to timer_sleep(), including the 
+>> actions performed by the timer interrupt handler on each timer tick.
+
+>> A3: (2 marks)
+>> What steps are taken to minimize the amount of time spent in the timer 
+>> interrupt handler?
+
+---- SYNCHRONIZATION ----
+
+>> A4: (1 mark)
+>> How are race conditions avoided when multiple threads call timer_sleep() 
+>> simultaneously?
+
+>> A5: (1 mark)
+>> How are race conditions avoided when a timer interrupt occurs during a call 
+>> to timer_sleep()?
+
+---- RATIONALE ----
+
+>> A6: (2 marks)
+>> Why did you choose this design? 
+>> In what ways is it superior to another design you considered?
