I did one quote per mark, occasionally had more than necessary just to make sure, and also most of the time I finished on the given lines. Got a B6. If you have good analysis you'll get the marks.

Ended up getting a mid band 5 lol, so turned out well.

how do you even do this. Are you supposed to use snells law or something whatt...

Any ideas on what their 'favourite' topics are?

How much marks do u guys reckon you'd lose for having k=5 for that question, for some reason i didn't realise the question said x^k and x^(k+1) and rather just saw k and k+1 and did the whole procedure correctly, but with the wrong terms or whatever lol.

Uranium has some binding energy whatever it is, but this nucleus will be relatively unstable so we can imagine that the binding energy is not so high to begin with anyway. It does say "Total Binding Energy" so when the Uranium splits into the Thorium and Helium, it has now become more stable...

For part (i) of course you would find gradient of AP and gradient of AS and just prove the product is -1 but would you be allowed to just write down the tangent equation (to find coordinates of A) without deriving it, and just state its from reference sheet or something? This would save a little...

If you choose any pair of shoes with no restriction, the chance of you getting it is 8/8. Now you have a restriction, the next shoe has to match the colour of that first shoe, which is only a 1/7 chance. Therefore (8/8) * (1/7) is just 1/7. This is the more 2u way of doing it.

Unlikely they'll ask the exact same question of course. However, you may see some similar styled questions every once in a while, but it's not abundant.

Expecting a solid b2, maybe a b3 on a good day lol, this subject kills me

It seems like there's not many of us doing the Dobson poems. How'd you feel about the understanding of ageing? I think I was able to make it work somehow but tbh I really don't know. I did Cock Crow, Amy Caroline and Young Girl at a Window.

was hoping for 93+ but might have to settle for for less at this stage.

Ok wow that helps a lot thanks!

What about that 2.5kN force? Why do we disregard that?

And also, they're analysing joint C?? I though BC goes through C so how can you analyse joint C since BC goes through C?

That's the sample answer, and it says BC=0. What I am I doing wrong in finding BC? I'm using method of sections where I've cut through BC. And this is my equation (which is wrong): \sum M_a = 0 = 5(2.5+BC)

I'm screwed for this subject lmao, especially materials I'm terrible at

The Uranium nucleus are split, so the total mass decreases because the Uranium has decayed and used energy to decay to Thorium and Helium. As for total binding energy, one way to think about it is that the nucleus of the Uranium is relatively unstable, so it has somewhat of a low binding energy...

Probably not ahaha. It'll likely demotivate me more than anything else lol.

Well it looks like I'm getting a band 3 or band 4 at best for engineering 😔
