Another homestretch

Posted by bernicky - July 21st, 2015

Next Tuesday is exam day. From 8:30 in the morning until 16:30 is exam time. Two exams both with a required passing grade of sixty-five percent. No matter how it plays out it will be a load off of my shoulders. Studying has been taking up a lot of time for the past year and a half not that I will be off the hook when this is done but the next courses of study are more my bailiwick. First I have to get through the exams.

Something occurred to me today while studying: if you can remember one key component then the rest can be sorted. Here’s what I mean. I’ve been having trouble with calculating voltage, current and resistance. It’s just something about the letters used that screws me up. There are three basic calculations but it dawned on me that I don’t have to know them I just have to know one of them. Voltage divided by Current equals Resistance. I don’t know why that one sticks but it does. From that the other two are easy to figure out Resistance times Current equals Voltage and Current equals Voltage divided by Resistance. It’s not a shortcut per se it’s just realizing that some of the things I will be tested on can be figured out as long as long as some basic formulae are committed to memory. Some of them are easy to remember some are difficult. I always have a problem with anything to do with spheres – surface area or volume. 4 pi r^2 and 4/3 pi r^3 respectively but they always seem to abandon me when I see the question.

It’s all going to be water under the bridge by Wednesday next week. By the end of August either I will have my ticket or I won’t. Either way if I am going to hang on to the house I’m going to have to get that second job I’ve been waffling about for the last year.
