CS 471 Planned Schedule, Spring 2022

Programming Assignments:

• All programming assignments will be posted and announced as early as we have them prepared, generally with at least two weeks to complete.
• These dates are subject to change as needed during the semester.
  • Programming Assignment 1: Jan 28 - Feb 11 (due by 11:59pm)
  • Programming Assignment 2 (Part 1): Feb 22 - Mar 11 (due by 11:59pm)

Homeworks:

• There will be approximately seven homeworks, which will be assigned through Blackboard, but will be done on Gradescope.
• You may work with up to one partner from your lecture section.
  
• (This does not have to be the same as your Project partner)
  
• You will have about a week to work on each homework assignment.
• In general, all homeworks will be due at 11:59pm on Saturday Nights.
• Each Homework will only take an hour or two to do, but I'm giving 6 days for your own scheduling and planning.
  
• The planned Homework Dates are in the Calendar Below
  

Tests are bigger milestones, and their dates are announced ahead of time.
Only severe scheduling anomalies would force a delay in test dates.

• Midterms (Section 001 / Section 004):
1. March 9th (Wednesday) / March 10th (Thursday)
   • OS Structures, Processes/Threads, Synchronization
     
2. April 20th (Wednesday) / April 21st (Thursday)
   
   • Scheduling and Memory Management
     
• More information will be provided as the date closes in.
• The exams will be done In-Person during our normal Lectures.


• Final Exam: See Exam Schedule for the Date and Times.
  • https://registrar.gmu.edu/wp-content/uploads/Spring-2022-Final-Exam-Schedule.pdf
    
  • The Final Exam is Comprehensive
    
  • The Final will be taken In-Person in your normal Classroom at the specified dates and times.

Below is a tentative schedule, which is subject to change as needed.

• This is the Planned Schedule of Topics. 
  
• Individual lectures may vary, but this this the plan.
• Each week indicates the plan for each of the two lectures for that week.
  
• Dates may change as needed based on the pace of each class.
  
• Note: March 14 - March 18th is a Holiday (Spring Break)

Note: The Video Topics are NOT lecture recordings.  (This is a fully in-person class)

• They're supplemental topic-based videos that cover the same material as the slides.
• In Class, we'll be focusing on guided discussions, live programming, and working with the algorithms and concepts.
• We'll talk about these during the first lecture.
