16. Lab Assignments There will be weekly lab assignments.
The labs will count 30% of your final grade.
The assignments are usually 1 week assignments, sometimes 2 weeks for the less small ones.
The assignments will be closely connected to the class content. Working on them will show you if you really understood the topic.

17. Lab Grades Labs will be graded as follows:
On time: max.10
Late, max: 6
The TA and Instructor are here to help you. Do not wait until the last minute if you are stuck !
The TA/Peer Teacher is NOT ALLOWED to solve the problem for you!!!!

18. Programming must be learned by doing it !
Policy on Cheating
Programming must be learned by doing it !
Copying another student’s program deprives you of that learning opportunity.
If a lab assignment is found to be a copy, both students will receive a –10 for that assignment.
If more than one program is found to be a copy, the students involved will receive an F for the course.
