ever walked out of an exam and felt about this small whether it be the result of poor studying or a terrible professor I think most of us have been there at least once or twice these tips you're about to hear have been curtailed toward engineering majors but feel free to tweak and mold them as you please there are several obvious ways to improve exam score studying reading textbooks doing your homework but will be taking a different approach in this video this is how to pass an engineering exam tip 1 if you don't know it assume it professors would much rather you pull a random arbitrary value out of thin air than proceed to solve the problem neglecting it all together here's an example in fluid dynamics suppose your task is to calculate the power of a pump required to drive a liquid through 1,600 feet of 8-inch pipe our friction factor is 0.005 average pipe velocity 10 feet per second mass flow rates 10 slugs per second and acceleration due to gravity 32.2 ft/s^2 and all we need to do is calculate head loss from this equation and multiply that product by the mass flow rate and acceleration due to gravity once more this kind of math is 99% plug and chug basic algebra now let's assume for sick kicks that you cannot remember the head loss equation great there goes one vital piece of the puzzle while instead of stopping here panicking and turning the page as tears rolled down your face do this right assume in all caps I recommend head loss equals say 100 feet this assumption may have just saved your grade professors will look at this probably realize that this magical number is a complete fabrication mark off a few points for that and continue on grading even if this value proves to be way off chances are this is the only place you'll be penalized your final answer will of course be wrong but only as a result of your royal mistake a few lines up its placing a band-aid over a geyser but better than failing to write a solution however wrong it may be now let's move on to tip 2 if you're artistic in any way shape or form don't be afraid to draw pictures and/or graphs when necessary at this point it all comes down to how well you can pass off BS as legit work you can really get away with this one in your physics classes suppose your problem involves lifting a 10 kilogram box let's draw a box here straight up a certain distance say 10 feet but you no idea where to go from here draw a friggin picture start with the ground throw in some grass maybe a tree or to make it look pretty now we've got to get this box let's label it 10 kilograms up here 10 feet sketch an imaginary crane of sorts and our rope connecting it to the box in comes the Freebody diagram even if you cannot remember the force and work equations needed to solve this problem you more than likely squeak by with some partial credit just for this amazing work of art it reminds professors that you aren't clueless and that you genuinely tried and hey you sketched and labeled a Freebody diagram that wasn't even asked for if a problem instead pertains to a graph or trend that you can recall sketch that anything is better than nothing in an engineering exam tip 3 this will be hard for some of you maintain an adequate level of maturity don't write smiley faces or obscure question marks on exams these divulge your lack of know-how and nothing will cheer up an engineering professor trust me I've tried let's assume you're asked to name the chemical compound mg fe 7 SI 8o h 22 a magnesium iron silicate hydroxide if you might coming to night followed by a smiley face or classic LOL you deserve point deductions plain and simple by the way this is the official name for this compound ladies this isn't so much a problem for you as it is for us guys grow a beard and man up keep that maturity level on point especially when in test-taking mode tip 4 write neatly and in an organized manner you will thank yourself later I take this one very seriously check out my notes and in purple such a class I choose thread in all caps because it allows me to better differentiate legit notes from longhand equations if you combine tip 4 with tips 1 & 2 you'll be sitting good in the engineer neighborhood it's a bit like PC cable management it doesn't improve functionality in any way but sure makes things easier to find and change later on here's the last resort option tip 5 act like you misunderstood the question let's assume the question asks for the total resistance in a circuit with three parallel 5 ohm resistors if you can't remember the parallel summation notation this right here but you can remember the easy 1 resistance in the series and pretend the question asks just that what is the total resistance in the circuit with three series 5 ohm resistors I suggest sticking with the word parallel though on paper and writing out the notation force Cirie's so as to fool your professor into thinking you simply mix them up which is much more forgivable than not remembering parallel notation all together again it's a last resort effort test-takers discretion is advised but there's one last tip I cannot go without stating that's tip six be confident even if you know without a shadow of a doubt that your answer is incorrect tips one through five will not work without confidence be confident in your assumptions confident in your sketches confident in your writing and be confident in your confidence it's like the old saying goes you can go anywhere in the world you want if you appear confident and carry a clipboard don't bring a clipboard to an engineering exam though that will certainly draw unwarranted attention bad news if you plan on stuffing functions into your handy graphing calculator yeah I know I've been there if you like this video like the tips
