Would someone be able to explain to me what a class and object are? Can't get my head round it

Object:
-An instance of a class
A real world identity
-It has attributes and methods

Class:
- A template for a set of objects that have state and behaviour

Good luck everyone 🙈

Guys could you predict what could a eight marker would be?

How did everyone reckon it went? I thought it was pretty good generally, the stepwise one I wasn't quite sure what they were looking for but other than that it was fine.

Can someone tell me what the answer should have been for the 8 marker about CIR and the 6 marker about scope? And can someone draw the stepwise refinement thing too. Thanks

Not a correct solution
find p
set p as hand_brake

can't remember the exact syntax.

Explain what backtracking is ...
Show what steps 12,13,14 would be ... which you use hand_brake as P
Use those steps to explain your point ...
6 marks in the bag.

That paper was amazing. No way I dropped more than 20 marks at MOST.

Maybe OCR felt *****y over last years shenanigans for f452???

I have a feeling most of us needed that paper after those football and off-syllabus questions :')

56/100 was an A for our year, so thinking they're trying to balance the grades???

Last year was fairly easy ... so If I was you I'd go according to those boundaries ... add a little more to be cautious ...
I'll tell you what they were ...

A was 86 Marks ...
B was 75 Marks ..
C was 64 Marks
D was 54 marks ... etc.
If you got an E in that paper .. you either didn't give a **** and didn't revise or were half asleep.

Yeah .. you can expect them to be similar .. maybe add 2 marks to each boundary to be realistic.

Ehhh, I'm sure I made some mistakes, it's really hard to predict what way the markscheme will go on some questions. I'm pretty sure I ****ed up the backtracking question, but it was only 3/4 marks I believe so I'm not too worried.

They were so nice with the 8 marker, and the fact there were no trees was a complete blessing. No BNF was a surprise also.

That was actually an okay paper.
