How long time take a stedent do a test
I Have experience to improve my students the best way to present a test, just do a review with them step by step to giving them the trust in the subjet and then prove their knowledge with question that rise in four setions, by sample 10 questions exam and up to 40, 60 and so on till they adquiere the expertise. this is the way I training all my students for the test time
I have a similar experience with tests. Some will use any and all the time you give them and more.
I have come to learn that regardless of what I do to prepare a student some take forever to take an exam! I have put time limits on them - so they have the entire class to finish the test and that's it. It seems to get my slow one's moving a bit faster.
The teacher should know enough not to make a test so long that it will last longer then the class period; make sure the student is aware of what types of questions will be on the test; through the review session.
