How To Write A Good Wrong Answer

As you can see from these pictures, if your wrong answers have the same (or even partially same) range as the correct answer, you’ll get confusing choice options. 

Also incorrect answers shouldn’t match themselves!

Now what you can do to avoid these problems.

          1. Use the “never” operator and !! when making up variables, if the range is wide enough. 

If the range is narrow, you will get errors like this quite often (please, rebuild your question at least for 20-30 times to see if it works fine):

If too many conditions are used - this might be causing errors too. In these cases use the tips below.

          2. Another easy way to make wrong answers is to define them regarding the correct answer. For example:

There are two tricks here: 

• To make it unpredictable whether the real answer is somewhere in the middle of the values or the biggest or the smallest one.
• To make the wrong answers so that their ranges do not cross.
