AverageMultiChoiceTest Ahh please don't use the pen with a rubber, the erasable one
The pen ink disappears in heat/through friction.. if left in a hot place like under the sun or heater, the work will disappear
Even if it's unlikely that it will be affected, you never know where the tests will go and if everything disappears it'd be terrible
Also, another hot place where the pen will disappear is in a photocopier, so if they decide to put it in one, everything gone
