This one is for free: stay tuned at the end though.
- Go with your gut. If that fails, narrow it down by elimination. Failing that, continue below.
- It is easier to write a false statement than a true one for a test, so about 60% of true/false test questions will be false.
- About 70% of all multiple choice answers will be a middle choice. So, for five choices, 3 or C will be the answer. For four choices, 2 or B, or 3 or C will be the answer, and the third choice is most common.
- In the event one option is "all of the above" about 75% of the time this is the answer. "None of the above is 50% or less.
These strategies only work if the test designer is not aware of the human behavior normal in test design. Being one of those people, my assessments were one third true/false divided 50/50; one third multiple choice of only four options and those were divided into 25% for A, B, C, & D; and one third essay.

How do you make chart of open ended questions?
I'm not sure what the question means but here we go with an answer. Open ended questions are one that when asked can not be answer with a simple yes or no. The answerer must elaborate, explain and otherwise embellish in order to give an answer. To ask an open ended question you don't as "why" but rather "what" and "how". Until you get used to asking such questions a good idea to write them down down ahead of time until the become second nature to you. There are statistical programs that can categorize open-ends. You could then create a chart based on the number of comments in each category.
