grading guideline/key

To save time, I will be using the following shorthand to grade papers.

"dnf" .......................................... does not flow
"flow?" ....................................... non sequitur, work does not flow 
"i.e."........................................... inefficient; supporting work is correct, but it is round about and inefficient
"m.c."......................................... make corrections
"m.s." ........................................ missing step
"r.a."............................................ reasonable answer, "Was the answer reasonable?"
"s.w." ........................................ show work
"o.k." ......................................... usually used when a supporting argument is accepted, but was done in an unexpected way
"o.a" or "o.k. as" ........................ the work is correct, but used incorrect variable or value(s) from a previous step
"NL".............................................not listening? as in, you're listening (or doing) to what i taught you.

You will receive very little credit or no credit, if 
  • the solution contains little or no relevant supporting work that lead to the answer.
  • your answer is not in the expected form.  For example, if a questions asks for a linear equation in standard form, your answer should be an equation form of some sort.  Writing the answer correctly in a wrong form will earn some credit, but writing the answer as a point (2,3), which is not an equation, will earn NO credit.
  • your incorrect answer could have been prevented by checking it.
All answers must be complete, legible and simplified to lowest exact terms.
