Hi DND Dan
I actually just registered 5 min ago to help answer your question! I've actually put in for NCM-SEP into ATIS and I find out if i made in a few days, so we might end up working together!
I'm already enrolled in school, BCIT, doing the Electronics Core Common course which covers all the same ground as POET and some of the QL5 stuff to boot (as i understand it, don't take my word as gospel).
I'm only about 7 weeks in but we have covers some of the following basic (as in everyone needs to know this, eg POET) electronics concepts;
(All D/C so far)
Soldering and resister code reading
Ohms Law
Kirchhoff voltage law
Kirchhoff current law
voltage divider
current divider
series circuits
parallel circuits
series-parallel circuits
resistance
voltage
current
conductance
Wheatstone bridges
ladder networks
superposition theorem
Thevenins theorem
Norton's theorem (same thing as Thevenin Voltage (Vth) divded by Thevenin Resistance (Rth) with the Rth now in parallel, doesn't really count!)
power formulas
max power transfer
A whole bunch on capacitors
Magnetism
Electromagnetism
troubleshooting series, parallel and series parallel circuts
Ive no doubt forgotten some stuff already, but if you just learn even one of the above ahead of time you will be doing yourself a huge favor.
Everything here is pretty much interrelated, but if I was in your shoes, id study up on Ohms law, Voltage, Current, Resistance and Kirchhoffs laws.
Just by doing that you are giving yourself a massive head start.
I'm told A/C makes D/C look nice and friendly, and I'm beginning to believe it.
Knowing D/C ahead of time will give you more time to get familial with A/C and get threw it!
As for mathematics you will need, no if and or buts;
very good algebra
understanding slope and positions on a Cartesian grid
firm to excellent understanding of scientific notation (and engineering notation)
understanding of logarithms and log base (ln and e too)
excellent trigonometry skills, if you cant handle sohcoatoa, get started now as it is a must with polar coordinates
Also, start doing logic puzzles, they are a massive help with troubleshooting D/C circuits (maybe A/C too? don't know, not there yet)
Ive set my army.ca account up to send my main email emails if some one PMs me, so if you have any questions, Ill get right back to you!
Hope everything goes well for you, and look forward to seeing you bashing electronics with me down the road!
