     * Be suspicious: If you see similar, very wrong answers, flag the tests and compare their answers to other questions. Hopefully you can look out for cheating while the quiz/exam is actually going on, but you won't be able to see everything.     * Be suspicious: If you see similar, very wrong answers, flag the tests and compare their answers to other questions.

-===Scantron Exams=== 
-    * You'll grade these kinds of tests with your fellow GSIs. 
-    * Have a few people people double-check the answer key Scantron //for each version of the exam// **BEFORE** you start running all the tests through the machine. 
-    * Note any questions that are missed quite frequently. Reasons for this can include: 
-       *The question was poorly written or possibly too hard 
-       *The students just didn't know that material very well 
-       ​*There'​s an error on the answer key 
-       ​*Something went wrong with the machine or the answer key Scantron 
-    * Note any one student who missed a TON.. Reasons: 
-       *They really just don't know what's going on 
-       *They marked the wrong test version (you might be able to re-run it through the machine with the correct answer key or their GSI or the Head GSI might have to grade it by hand) 
-       *They used some writing utensil that the machine doesn'​t like (their GSI or the Head GSI might have to grade it by hand) 
-       ​*Their test is too wrinkled or has coffee spilled on it or whatever (their GSI or the Head GSI might have to grade it by hand) 
-       *Use your judgment here; it's annoying to grade a Scantron by hand, but if they really just accidentally spilled something on it, then you should probably grade it by hand with no penalty. ​ If they'​re dumb enough to mark the wrong test version, well, they might deserve some extra points off for that. 
-    * It's a good idea to skim over each of your student'​s tests to see if there were any obvious bad erasure marks or anything like that which may have led to an answer being marked wrong unfairly. ​ However, don't feel bad if you don't catch every one of these -- your students will not miss any!! 
-    * Like after quizzes, strongly consider talking to students in your section(s) who performed very poorly (grades of less than 40% or 50%).
