NESA do say that 2B pencils are recommended if drawing diagrams.

Well, there's heat energy that's wasted with eddy currents that form around the iron core because of electromagnetic induction. Because it's alternating current, you've got changing voltage and hence a changing magnetic field created in the primary coil. There is then an induced emf in the...

Maybe they're referring to double-slit diffraction? It could be split by the slits then combined again because of constructive and destructive interference. I still don't know how to explain the intensity though... maybe a Physics guru could? Also, what paper is that from?

I don't mind the questions on the progression of Physics discoveries and technology over the years, so hopefully they keep up the trend.

I hope that it's not super hard, although I wouldn't mind it if we were carried by scaling moreso than last year.

Yeah, that wasn't as bad as I thought it would be. The essay question wasn't difficult as such, but it was interesting that it applied to all modules, a first for NESA.

^^^^^^

I have one up my sleeve, although I'm praying that they don't ask for it. Having said that, we might get scaled up if they do because it'll be the first time they would ever have done it.

Yeah, I got D too.

Question 11 and 12 were reasonable, but some of the multiple choice and Questions 13 and 14 were pretty difficult. I got some things though, and I did my best so that's all I can do.

Yeah, I think last year's test was so much harder than this year's. While there were only a few difficult questions, the majority of it was really good. I think it's funny too that NESA have been somewhat nice to us by putting our names and numbers on everything.

Hey, extension 2 students! Have you started your projects? Any exciting ideas? 😊

I haven't seen it around yet. But today's paper was pretty fair. There were a few hard questions, but apart from that the majority of it was doable.

Atonement

Yeah, pretty much. I set up lines for how you'd normally do isometric, then did the rest freehand and tried to make it look as neat as possible.

It wasn't as bad as other hsc papers I've seen, but there were some things I wasn't expecting. They even asked us to draw freehand!

Yeah, I didn't see that coming either...

Yeah, I got something like that.

Yeah, I felt that way as well during reading time. But after dedicating most of my time to the glider and truss questions, I felt pretty good. Some things I'd forgotten and I doubt I'll get full marks, but I did the best I could with that paper.
