First class of dive course at CWRU:
Older Navy diver instructor walks in "So I know each of you is coming into this class with different levels of experience. What we're going to do first is a short test on your proficiency for 20 minutes.
It will be graded on completeness, not correctness. You are not expected to know all the answers. I'm just interested in gauging what you know.
Be aware, there are a lot of questions for the time, so I suggest you work quickly to get through all of them. Make sure you read and follow all instructions.
Do not turn your paper over and start until I've handed all of them out and said go.
hands out tests
Go."
12/14 people in the class start furiously scribbling
The first sentence on the test?
"If you read this sentence, please continue to hold your pencil, but do not write on this test. Wait until time has expired."
It always stuck with me as one of the best lessons about diving. Both in what you should do, and what our natural inclinations to actually do are.
- s_dev 6y agoOther versions of this test include the last question being "Don't answer any questions". The habit the teacher was trying to impart was "read the whole paper" first before answering any questions -- particularly if there are multiple choice questions.

- throw1234651234 6y agoThis is an irrational party(professor) trick that wastes everyone's time. An argument could be made for "read the (short) instructions at the start". An argument cannot be made for this. There is often very little value to skimming the entire question set before the exam.
- henshao 6y agoI don't know about you, but for my tests on a curve where I might not be able to answer all the questions, doing the quick skim to answer the low hanging fruit before getting to the harder problems is a good way to make sure you don't run out of time and lose out.
- dllthomas 6y agoAlso, content of later questions can be useful earlier, and getting some background brain cells working on the hard stuff while you churn through the easy stuff could be worthwhile. It's a good lesson, but it's a lesson about taking tests not about the material. I can see arguments for and against including that in any given class.
- Nadya 6y ago>content of later questions can be useful earlier In some tests I have seen future questions answer previous ones. For a contrived example: "Q1: What color was the bookshelf? A. Red B. Green C. Blue" "Q2: What sentimental item did John take from the red bookshelf?" I was never sure if it was on purpose to reinforce reading all questions before answering or if it was merely poor test design. Usually it was more subtle than my contrived example but it did bump my scores on some tests up a bit.
- kemitche 6y agoI did the same, but if I'm doing that skimming and I know the answer to question 12 is (c), I fill in (c) and keep going. I don't read all the questions, then go back and try and remember which of the questions I knew the answers to off-hand. Instead, I'd do the test in 3 passes. 1. Answer all questions that I know the answer instantly or (for math type tests) can solve within a few seconds. Skip anything not quick. 2. Go back and answer questions that I know I can solve. These usually take a minute or two (since the easy ones should already be done). If there happens to be a question I know I can solve but also know will take "too much time," skip it. 3. If there's time left, work through any remaining questions (hopefully there aren't that many), making a best effort to prioritize the ones I'm more confident that I can solve in the time remaining.
- watwut 6y agoWhy would you not answer questions you know straight away? That wastes time.
- pengaru 6y agoIt's been a very long time since I had to do any tests, but back in my school days, with multiple-choice tests, I evolved a method of quickly answering everything I was confident to know 100% throughout the entire test in a first pass, reserving the rest for subsequent increasingly slower passes. What tended to occur was the earlier fast passes at the very least warmed up the cache upstairs, and some previously unclear questions became obvious. Then for the remaining questions, they often had dependencies with other questions and their answers, which I could use to deduce probably correct answers. This was obscenely effective. To the extent that I would ace tests in classes I barely attended and never turned in homework for, in some cases culminating in teachers publicly accusing me of cheating on the exams. Though some of that was also due to switching from private to public school where I had already learned the material in the previous years.
- travisjungroth 6y agoI once used this method and spent the last ten minutes of a test just guess-and-checking the solutions to a question I didn't remember the formula for. Of course, it was the last one I checked. (I wasn't confident enough to early return).
- Griffinsauce 6y agoI used the same method and can confirm it was very effective for me as well. An added bonus is reduced stress about time limits. After the first pass you have a big chunk (if not most) of the test done in little time - this feels good and also leaves you with a clearer idea of how much work and time is left.
- watwut 6y agoI agree. More over, half of these have genuinly mutually exclusive instructions. And from those mutually exclusive requirements you are supposed to pick the "least likely one" else you are wrong. It is good example how manipulation works however. You put people into unsolvable situation and then blame them.
- mjevans 6y agoOne of my middle school teachers gave that sheet out to the class. I was that one kid that took it seriously, but had no prior-example knowledge to even bother reading ahead. The test with the bail-out at the start sounds logically fine. The test I was given was just a cruel trick from a trusted source of tests / knowledge provision.
- Nursie 6y agoWe had a Chemistry teacher who tried a similar sort of thing on us when I was about 17. "OK class, today's lesson is going to be a dictation, get your books out and start taking this down" I can't remember the exact content but effectively he started off with some familiar organic chemistry and then veered off to stuff that was pretty obviously wrong. I'm proud to say that I'm the one that said "Eh ... that doesn't seem like a valid equation ... ?" "Good! Never just copy this stuff down without engaging your brain!" (Or at least that's the way it goes in my memory, 17 was a long old time ago!)
- nkassis 6y agoI was not a great student but at one point in college I realized that I wasn't listening while taking notes. I was just mindlessly copying everything exactly as was written on the white board missing out on what my teachers said. I stopped taking notes at this point and started paying attention instead. My grades improved. This might not work for everyone but something to try if you struggle retaining lecture content even as you take a bunch of notes.
- andrekandre 6y agoyes, ive had similar experiences, and thinking back on it, why take notes when you can just record the lecture and play it back later.... better to engage in the lecture, since thats why we are there in the first place!
- sigg3 6y agoFunny, for me it's the opposite. Can't remember it if I don't write it down. I don't have to read it afterwards, I just remember what it was by remembering writing it.
- stjohnswarts 6y agoIn a physics or maths class that seems impossible unless the prof is teaching directly from distributed notes or the text book. Some of the better classes I had were those where the prof just gave out their notes and we could focus on what was said rather than writing it out, in that case if you zone out it's your fault.
- grawprog 6y agoWe had a similar one of those in school. The first question of the test was 'read all questions before you start.' Then it had stuff like poke holes in the paper, draw things, random stuff, the very last question though was, 'Now that you've read all the questions, just write your name in the top corner and turn your paper over.' Yeah...a lot of my classmates ended up with holes and scribbles on their tests...
- ant6n 6y agoIt’s pretty ambiguous, though. In tests you usually complete all questions. Why should you in this instance only complete the first and the last task?
- grawprog 6y agoThe teacher also told us specifically to read everything before also doing anything.
- watwut 6y ago1.) The complete set of instructions was inconsistent and mutually exclusive. The two questions required mutually exclusive actions. Why pick last? 2.) That is standard boilerplate typically said due to people not reading whole questions. And it is not useful advice in general.
- lakis 6y agoWhen you are doing a safety check list, you don't skip and do whatever part of the checklist you feel comfortable doing. You do it from top to bottom. Multiple people have died in accidents because they focused on small issue ignoring the larger problem. So when it's time to check safety in scuba diving, you should better follow the instruction instead of doing whatever you want. Example. There is no point to worry about "Is your mask clean?" when you are going to run out of oxygen and drown.
- dylan604 6y agoIf you are still unsure of the why, then you have had a fortunate life. There are many times you will get a set of "instructions" where somewhere something is wrong or incomplete, but you won't know that until you've worked your way through them. Ikea comes to mind. It is often very helpful to read through all of the steps involved first to make sure you actually have all of the parts/pieces you need and to make sure they make sense before starting. So I say again, that if you've never run into one of these situations, then you've been lucky.
- watwut 6y agoThose who followed first sentence instruction did correctly one question. And ignored all the others in test that was supposed to be graded on completeness. He also claimed the goal was to gauge their knowledge. Again, that was lie. And those who scribbled were literally trying to fulfill stated goal of test. > It will be graded on completeness, not correctness. You are not expected to know all the answers. I'm just interested in gauging what you know. In overwhelming majority of situations, of you sabotage goal of event due to following likely faulty mutually conflicting instructions, you will be blamed for it.
- ethbr0 6y agoGiven a set of mutually conflicting directives, one must exercise discretion to prioritize. I felt (at the time and reflecting on the experience now) that it was clear which held the higher priority.
- watwut 6y agoTo me, ignoring that one and answering questions gives more sense. According to instructions, the test was judged on completeness. The instructor expected the students to pick set of instructions that make test less complete. In this variant, answering majority of questions and leaving that one missed is rational behavior.
- cozzyd 6y agoThe test was graded on completeness no doubt. Grade = completeness == 0 ? Pass : Fail.
- ethbr0 6y ago> Make sure you read and follow all instructions. I'd be worried about someone who receives that instruction, receives an anomalous instruction on the test, and decides to ignore the anomalous instruction.
