I am writing on this forum because I'm extremely troubled... I recently had a quiz in my "Project Lab" for which I just received my results. ...The entire course revolved around building a variable power supply. There was no theory class to support the lab. ...Before receiving the marked test back, I had learned that half our class (it's broken up into two sections because of size) was allowed to use the internet/google as a resource! The first half of the class which I was in was only allowed to use our notes. ...I was quite frustrated by this and brought my concerns to the teacher... to which he responded "their test was harder".... My response was "I guess we'll see when we get our results back, won't we".... Because I did not feel comfortable with my answers at all after writing it, and I believe that half the class had an unfair advantage, no matter how much harder their test was.... With a resource like Google and the internet you can do quite a lot in 2 hours! ...while our only resources were what we brought to class with us. ....Enough students complained... The teacher told us today that there was a 2% higher average for the part of the class which was allowed to use Google to find answers on the test, so that 2% was added to the first half of the classes total marks. Well... I received my test back today, and am extremely disappointed with the results.... I have attached a copy of the entire test for people to review... I am actually quite concerned that some of the questions were WAY too vague, and in some cases marked incorrectly. Here is the Quiz (which is actually worth 15% of our course mark!) ....it's horribly written but it looks like my final mark was 9/17 page1 page2 I realize that I made some legitimate errors... However without a resource like the INTERNET it was the best I could do.... And I do have some concerns with the questions and the way that they were marked, and would like a second opinion (or many). Question 1.... If you reverse the leads on a potentiometer (the one that controls voltage on the variable power supply) ...you would change the direction in which it needs to be turned to increase or decrease voltage.... Am I not correct?... can anyone see why I got that wrong?! Question 3.... This question pertains to Soldering paste. It asks to circle the most correct answer. (which A and B are very similar) .... My reasoning for picking "A" was because I have the understanding that the danger with solder is the cumulative effect of lead in the human body... (which is much more serious than temporary harm to your lungs) ...here is an example of Solder Paste MSDS proving my point http://www.gcelectronics.com/order/msds/123.pdf Question 8.... It simply asks to state ONE purpose of the ground terminal in a power supply...(as described in question 7) .... HOW is my answer incorrect?! ...the rest of the questions/errors are probably legitimate... Although questionable as to whether it was ever taught in class... I do have a particular issue with Question 12) b. ....HOW does a capacitor INCREASE voltage in a circuit!? WHY would the voltage ever be greater than it's input!? ...Any opinions/input would be greatly appreciated!
