Any advice on getting head aroundPrinciples of science

[Jonesey]

hi all, just after a bit of advice. I’ve started level 2 2365 home study, completed all the health and safety which was fine but now started unit 202 and was winding if anyone has any advice when it comes to not being able to get your head around certain things like the mathematic principles

What specifically are you struggling with?

second sparkychicks post. we need you to be more specific.

Most of the mathematic principles, the learning material from the college only has give or take 2 power point slides for each - ultra fractions, decimal fractions, algebra, transposition of formulae, indices, notion, trigonometry, Pythagoras etc. But I feel like I need to understand it more than the basic explanation that they put in their power points, it’s not even enough to answer the worksheet

Look for posts by SpunkyWads... specifically a document he posted which covers Maths. Looks like a fairly detailed document about the maths you're going to need.

If you're still struggling, there are some excellent on-line resources about fractions and things like transposition, so a Google search for things like 'maths fractions tutorials' should yield some good resources.

It's hard to explain some of this stuff on-line as I usually reach for a pen and paper, but if you post specific questions with your answers, I'm sure I or someone else will be able to take a peek and point you in the right direction.

Brilliant thank you all ! Just what I was looking for

Hey, I'm currently studying level 2 as an evening course at a college.

I find this website a useful revision tool

2365 Index - http://www.swindon-massive.co.uk/electrical/revision/2360pt1/2365_index_page.htm

Also this textbook contains a lot of useful info regarding the course

I think you're overthinking most of what you have to learn. Chill out and take it as it comes.

One of the easiest ways to learn formulas and transposition is by learning how to use formula triangles. Learn these first and the various formulas you need and build upon that.

It seems like a lot of complicated mathmatics involved but if you break it down into little pieces it's really not that difficult.

I think this maybe the case but just feel I should fully understand it before I move one

Absolutely. But don't allow yourself to get overwhelmed is what I'm saying.

I'm on my Level 2 2365 at the moment, and I had this exact issue when I first started. The hardest thing about 202 is actually remembering all of the formulae, what each of the symbols mean, where they should go, and how they relate to one another as there are quite a lot of them - the actual maths side of it is relatively easy as it's just basic addition/subtraction/multiplication/division in different combinations so don't worry yourself too much about that, it can all be done very easily with a calculator once you know where to put them.

The learning curve is pretty steep at first because you're trying to wrap your head around multiple things at once, just persevere and stick with it and it'll all soon just click.

The "Basic Electrical Installation work Level 2 (7th Edition)" by Trevor Lindsley has been a huuuuuge help, it's useful not only for Science and Principles, but also 203 Installation theory and loads of other things too. If you have means of getting it, I definitely would.

And as Jonny G said, Swindon Massive was invaluable for practicing ohms and Kirchhff's law and it has a bunch of useful practice exams pertaining to the 202 unit (Beware though that it's not all perfect, so use it as more of a guide rather than a bible).

Good luck to you friend, you'll get there!
