Activity networks don't tend to appear frequently, as do a few of the other UML diagrams so it might be worth focusing on those. Other than that, almost all topic areas seem to have been covered in varying depth throughout the specification so far, so providing you've got to grips with all the past papers, it's unlikely you'll have any significant problems.

Activity networks?

Activity networks?

I assume he is refering to activity diagrams, a type of flow diagram used in UML. They have appeared in the Jan 2012 paper.

Does anyone know if you're required to explain your working-out in full sentences like the mark scheme for question 4?

I think any kind of full working will get the 3 marks, as in previous years with no working at all I think the answer was worth 1/3 marks. I use a different method of working for the binary questions, by calculating the values of the exponent and mantissa then plugging the numbers into standard form.

Do you reckon it will be harder considering it's only retakes who are doing the paper tomorrow?
Are there any specific topics due to come up in tomorrow exam?

The closest reference point - f451 2016 - was no harder than past exams, maybe some of the terms were less frequent and more obscure, but as long as you knew them it was fine. I would expect the f452 coding/algorithm questions to be more difficult to act as discretionary questions since there aren't many other ways to increase the difficulty of a paper. Considering this, i would also expect the grade boundaries to be higher.

Best of luck for tomorrow!

I agree, I was able to answer all the questions, but it was a lot harder than previous papers. Which is surprising considering that f451 was nothing special. Not looking forward to f453 after that...

That's the thing ... I didn't answer all the questions ... last 5 minutes I realised I saved an 8 mark till the end and missed out on the 4 marks for the last question. My psuedo code was for the first time messy af. but everything else was partially fine.

******s

I hope the examiner has the patience to read what I've put as it was extremely messy. I felt so pushed for time throughout and had 10 minutes spare compared to 45 for f451...
So glad I revised string manipulation the night before otherwise i'd have been ****ed.
Also what is up with the 6 mark serial file algorithm question having about 5-6 lines and the 4 marker at the end having a whole page. :angry:
