Re: need help with exam prep
If the test is an hour or more away from home get a motel to sleep in the night before. That way you don't have to burn up your brain cells and stamina getting to the test. You won't have to stress about traffic. If you go the motel route drive to the test location the night before. Scope out the test location; pay phones; parking; places to eat lunch; etc.
If any question does not seem to have a valid answer be sure to write it up and challenge the question. That way your answer might get extra consideration. Some tests allow this and use these exams as an opportunity to hone the test. For my contractor tests I did this on a few of the questions where the questions and answers did not quite match. I got 100% on the test(s).
Be sure so not make any gestures or eye contact that might be construed as cheating. Don't look towards any of the other testers that are nearby. I don't know how strict your test proctors will be but some of them like to make an example of suspected cheaters.
Find out if there is a penalty for guessing. If not, rule out the obvious wrong answers then take your best guess. If it's multiple choice and you can rule out two answers and are left with two that gives you a 50% chance of getting it right-- if there is no penalty for guessing. A guessing penalty means you get negative points for wrong answers, as well as positive points for right answers. The questions I hate are the ones that ask you to select all right answers in a multiple choice question and if you blow one part of the answer the whole answer is wrong. Find out if you get credit for the partial correct answer, or if you get dinged for the whole answer if any part of it is wrong.
Find out in advance what you are allowed to take into the test, and take everything that is permitted. There's nothing like getting to a test and finding out you are in fact allowed to bring in your sliderule-- and the nearest sliderule supply house is two hours away
If there is extra time on the test you can go back and double check your answers. However, your first instinct may be the correct answer and going back will only cause second guessing and more wrong answers. Personally, I like to double check and if I'm absolutely sure an answer is wrong I will change it-- but I don't second guess myself.
Good luck! Sorry not to be more specific.
