I think thus guy did 9c slightly wrong even though i go
t that

**** den! I got 123/4 for the triangle gg rip

Coordinates os S (-2.5,0)
COORDINATE OF T (43.5,0)

What actually happens with a re-sit? What goes on your record? What affect does it have on UMS? (if any) Amatuer hour over here.

Can anyone just explain the situation of a re-sit.

Absolutely nothing on there that hasn't come up in a past paper before or was really easy

People who did good know how difficult the exam was, people who found it easy are the ones who mis the questions thinking they did amazing. So, it's most likely this year was your worst paper attempt in these 3 years mate. 🙃😉

Nope. 90% sure the answer was 1/16 root 2 with a=1/16

Can someone tell me how u get 1/16 in question 2? Cz i got 1/16 root 2
