I think it went well this time. I'm really happy with the paper and the majority of my answers.

The first time I had 60 UMS, so a C. The second time I had 69 UMS, so a C again (the paper in January was horrible). I think I might get a high B or an A this time. Fingers crossed.
Gd luck mate.

Sorry, my school doesn't make you pay for the second time, and they don't charge you for the third as long as you do better.

I also take night classes at local college and they do make you pay.
Ok.

6. Wanna go through answers with me

7. How did you do 8b(I), proving L wasn't a diameter of A?

Subbed in the centre co ordinates. Didn't work so it isn't diameter
9. Find the intersection points the work the the length to them.

To be a diameter it must be 2 times the radius

10. The length of intersection was square root of 2 and length of diameter was 10

Did that then crossed it out without replacing it with anything! No idea why haha. The whole of B was 5 marks and for (ii), its ually 3 marks. So a loss of two won't be a problem. Plus I find M1 pretty okay, with physics helping me a lot!
12. M1!! Argh

13. I had this exam too today. Was quite easy to be honest compared to some past papers i did. The only part i screwed up on was logs part c but that was because i wrote down that it's 90x to the power of 5 instead of 2 and never bloody corrected it. Even though i had 30 mins to check my answers i somehow never noticed. however i think i might get a method mark for one of the conversions so hopefully wont lose more than two marks. As for integration, am i the only one who integrated under the curve and then just added the little triangle which was two?

14. Ye the total area under the curve was 16 and 2/3

Posted from TSR Mobile
15. i had 10/3 for the integration can someone tell me how you did it?

me too, but others didn't so I don't know who's right!

I had that too because area triangle was 18, and I took away the area under curve, but just realised this is wrong looked at it wrong
f******!!!!!!!

I did this too, but hopefully we can still pick up a few marks! Fingers crossed!

I did this aswell... I took the Area Under the Curve away from the area of the Trapezium, then added the area of the little triangle... :/ Probably only lose out on 1 or 2 marks, because the part they're looking for is the integration...
