    OCR AS-Level Computer Science Exam Discussion 2018

    Hello Guys! This is the 2018 exam thread for OCR AS-Level Computer Science (The thread for the full A-Level can be found here)

    Exam Dates:

    Paper 1 - Computing Principles
    4th June 2018 (AM) [1h15]

    Paper 2 - Algorithms and Problem Solving
    8th June 2018 (AM) [1h15]

    This AS-Level is fairly new and so there are very minimal resources for revision. However here are a few pages you may all find beneficial, including the old specification papers which although outdated, are still very useful for revision purposes.

    Resources:

    Specification

    Paper 1 Sample Question Paper

    Paper 2 Sample Question Paper

    Old Specification Past Papers

    Craig 'n' Dave Revision Videos (Of course some of these are A-Level only but a lot of them cover the AS specification)

    Official OCR Textbook (Sadly you have to buy it but it's great!)

    Tips - or at least my attempt at tips :

    Familiarise yourself with all the content before practising papers so you're prepared for them.

    Practice writing code, it will save you so much thinking time in the paper 2 exam.

    If you haven't already done them, save the specimen papers to complete last as they are going to most resemble the actual papers.


    Good Luck Everyone!

    I'm taking this course and I find it pretty annoying.

    I think this subject is really flawed in many areas, especially when viewed as a science. The algorithms and programming bit is for the most part fine and answers to any question have a logical basis. However I think every resource that exists for this subject is very sub-standard and the knowledge expected of the candidates is not made clear by the exam board.

    I've seen the same concepts outlined in many different ways, and it's not actually clear what the exam board approved definitions for a lot of things are in the spec, this wouldn't be a problem if either of the textbooks were any good at all. One is complete garbage that misses out entire portions of content, the other one is better but holds a good amount of irrelevant information, clearly misses a lot of relevant information and structures everything like a novel.

    The very limited amount of practice material out there doesn't seem similar to actual exam questions at all and answers aren't even included in the (slightly better) textbook, they're hidden away in a PDF only my teacher has. Pointless.

    The bit of this course about software development methodologies is about as far from scientific or objective as you can get, and is essentially just learning a drivel of antiquated *******s that some people made up in the 90s. Not relevant to most situations at all.

    Rant over anyways, I still reckon I can swing an A in this because a lot of it is not that hard but how this subject doesn't raise red flags for ofqual is beyond me.

    Hello everyone. Can you suggest me from which source should I study my Computer Science P3 for exam including what extra topic should I cover ?

    Hey, my name is Clive and I've come up with a very smart way of tackling every topic in the spec to get a high grade in the exam. I started using a modified version of Cornell Notes, due to the fact that when it came to mock time I thought my previous note taking skills and learning skills were good enough to pass. I kept dropping marks on things that I thought I knew in revision, which obviously wasn't true since I got them wrong. I agree with what you say

    That was actually not bad! Easier than I expected! What did you guys get for the Karnaugh map simplification? I got something like NOT C OR B, was that correct?

    Great paper until that Virtual Machines question came up...
    All you have to say was that the programmer could use the VM for testing the game out without having to buy the actual hardware, which is expensive, and the game might have been in development for an unreleased console, and so a VM would make sense. However, VMs are resource intensive, and so programming and testing simultaneously would be too much effort on the computers part!

    I spent more time talking about how the game can be designed for one OS but a VM is used to emulate the OS on another, and how it can emulated the necessary hardware. But I reckon there was more to say.

    That karnaugh map result is what I got...

    First time I've ever seen an exam correction...

    Yeah I've never seen a correction before.

    How was the question about memory / cpu management? What did you say

    I spoke about disk defragmentation, backing store management, paging & segmentation (spoke about both), and for cpu management, processor scheduling examples - round robin, FCFS, multi-level feedback queues

    The floating point question said it was a 5 bit mantissa but it was meant to be 6 (or 6 & 7)

    Was alright very hard to judge if I got written parts of the paper correct because there is a wide range of possible answers.

    Can someone link an unofficial mark scheme?
