If I could down vote I would.
Unfortunately he's got a very reasonable point
2. Can anyone please tell me how many marks I would lose for doing the trig question in radians instead of degrees ?? Would I lose like 3 marks ?
3. Someone please tell me how to do vectors part c because I'm pretty sure I did it wrong and I don't know why.

your constructive opinion is very much appreciated

65883852[/url]]Can someone tell me the method for the vectors part c question. I used the intersection point and +-1/6 vector AB but now I think I'm wrong.
That's right I accidentally done 3x AB instead of AB/3

It looked like some people got other values for lambda :/ unless I'm getting confused with questions haha
Can you remember the question? I could have a go at it to see if we get the same answer
7. Genuinely what do you think the grade boundaries will be for C3 and C4? I'm hoping for a D 50 UMS in core 3 and an A 80 UMS or a B 70 UMS worst case in core 4 in the hope that I can get 100 in D2 and last year's UMS will push me to an A overall. Don't think I got much more than 40 marks in C3 and 55/60 in C4 quite tragic considering I was initially aiming for an A* and now I'm not even sure if a B is reachable lol.

I can't, sorry it was involving the intersection of two lines and I can't remember the equations for the two lines

It's okay, I feel reasonably confident I didn't botch this one up
9. How many marks would I lose for multiplying the length of AB by 3 instead of dividing but doing the rest right

I am in a similar position, pretty much every class test I have done resulted in an A*, but now I don't even know. Will your university place be affected?
11. Can anyone remember the question where you had to find sinA and cosA cause i think quite a few root5's popped up but im not sure....
12. Someone help me by telling me the method to the part c of vectors tyvm i think i got it wrong :c.
13. Anyone remember Q4; the splitting fraction into ax+b+cx^2 etc? I completely messed it up 8 marks down the drain

I could not do that at all 😭

That's what I did, but I botched the numbers and used the wrong value for AB and got it wrong.

i think AB was like (4,-12,-20) or something like that.
17. Did anyone else need TWO extra pieces of paper?
18. Im sure 99.9% of these questions are right in order. Dont ask I have a way of memorising the questions, but if any are off which im sure none are plz note me. Took time to rite it downAttachment 552088552090Attachment 552088552090
P.S: im sure in the radioactive one, the initial mass had to be shown for 2 marks. In the paralelogram AB was 3 times CD

Yeah but I simplified that as 4(1, -3, -5) and used that for the rest of the question as a direction vector, because multiplying it by a constant doesn't change its direction, but for the last part I forgot to use the "real" AB and instead used my simplified version of (1, -3, -5)

It's awful isn't it I never thought I'd be praying for a D grade in a real exam I like to think that there's still a chance of getting an A but then again I don't want to get my hopes up. My insurance will accept me with a B but nonetheless it's heartbreaking to know that that grade isn't a true reflection of my abilities. How about yours? Hopefully it all turns out okay for us!
