General Marking Scheme

Mark	What you did
5	Reason, apply, problem solve, present: Correctly applies ideas to reach a clear, concise, correct, cleanly presented solution. Can reason about ideas presented. Can apply them to different settings. etc. Minor technical flaws allowed.
4	As in 5 but lacks some clarity, not as concise as possible, some minor flaw, not a clean presentation.
3	Semantics: Demonstrates correct understanding of basic definitions, ability to correctly apply basic techniques, theorem statements etc.
2	Some major flaw in the understanding of basic definitions, techniques, theorem statements. Examples are: Applies theorems to wrong settings. Does not understand the goal (ie tries to prove the wrong result). Solves the wrong problem.
1	Syntax: Ability to restate given definitions, theorems, techniques.

You can improve your mark by recognizing what you do not know this may sound strange. For example, if you know that your proof is incorrect, please say in what way it is. If you recognize that you can not complete the proof, please state that and why, what you would need to do to complete it. etc.
If you write up a proof with a major flaw and do not know that you have a major flaw, this shows a larger gap in understanding than if you recognize the flaw.
Be concise and clear, we will associate this with you understanding what the important points are and focusing on them. This means that you can think critically about what you are doing and assess its value etc. That you have a solid understanding of the problem capture ideas and present them.
