Tutorial 1 TA: Meriem BELOUCIF, Th 18:00-18:50, Rm 6573 at L29/30, firstname.lastname@example.org
You are welcome to knock on the door of the instructor any time. The TAs' office hours are posted at http://course.cs.ust.hk/comp4211/ta/.
Welcome to COMP4211! (This course was formerly called COMP328.) Tutorials will begin after Week 2.
Always check the Discussion Forum for up-to-the-minute

Always read before asking/posting/emailing your question. This forum is based
on modern, powerful software, instead of using the old clunky ITSC newsgroup.

All materials submitted for grading must be your own work. You are advised against being involved in any form of copying (either copying other people's work or allowing others to copy yours). If you are found to be involved in an incident of plagiarism, you will receive a failing grade for the course and the incident will be reported for appropriate disciplinary actions.
Warning: sophisticated plagiarism detection systems are in operation!
CollaborationYou are encouraged to collaborate in study groups. However, you must write up solutions on your own. You must also acknowledge your collaborators in the write-up for each problem, whether or not they are classmates. Other cases will be dealt with as plagiarism.
The course will be graded on a curve, but no matter what the curve is, I guarantee you the following.
|If you achieve||85%||you will receive at least a||A||grade.|
Your grade will be determined by a combination of factors:
ExaminationsNo reading material is allowed during the examinations. No make-ups will be given unless prior approval is granted by the instructor, or you are in unfavorable medical condition with physician's documentation on the day of the examination. In addition, being absent at the final examination results in automatic failure of the course according to university regulations, unless prior approval is obtained from the department head.
There will be one midterm (Mon 23 Mar, 09:00, Rm 4502, L25-26) worth approximately 20%, and one final exam (Fri 22 May, 12:30, LG1027) worth approximately 25%.
Science and engineering (including software engineering!) is about communication between people. Good participation in class and/or the online forum will count for approximately 5%.
All assignments must be submitted by 23:00 on the due date, unless otherwise specified. Late assignments cannot be accepted. Sorry, in the interest of fairness, exceptions cannot be made.
Assignments will account for a total of approximately 30%.
