It's useful to be good at maths but there is quite a lot of applying knowledge so don't think "I'm good at maths therefore i'm good at physics".
But I think you'll be okay it's not the hardest if you can grasp the content.
As has been said, only bit you really need to know if crashing is the Electronics/Electricity bit. I'd recommend you buy this book (it's expensive new, but the second hand ones are quite cheap and there's usually one on ebay, that's where I got it from!), very helpful book that'll help you catch up on the SG course bits you need : http://www.amazon.co.uk/Standard-Gra...9277635&sr=8-3
I do better in physics than maths however I find I tend to over think things in both subjects such as a physics question about why a set up was wrong the answer was a thermistor does not measure hours of light. I however epically failed by saying the heat given off by the sun may not be enough in order to switch on the thermistor thus it could be sunny weather however these hours of sunlight will not be counted.
My teacher laughed and said well you'll do well as an engineer with your thinking
I think along as your interested, I've found adv higher maths more "easier" due to actually enjoying it compared to higher.
How do you thing you've done in maths? I think I might get a B between 63-67% I take if its .5 of a percent they will round up?
Well at least I'm not the only one that's crashing Physics this year! It does seem rather, daunting, however, I believe with hard work and perseverance I may actually be able to get a decent grade by the end of the year
Our teacher has said the higher course is very different than the std Grade, but you just need to know the basics like some equations(Even tho they give you them) I have this great website with literately teaches you the whole course with notes and examples, Its like 400 pages so if you want the pdf pm me and i will forward you it.
