OCR Computer Science?

Haven't seen anyone talk about this yet. I thought I did really well on it (better than every other exam I have done so far) except I am annoyed that I messed up the Binary addition question because in my head I know how to do it.

It was OK. The legal and ethical with Lauren was difficult. Forgot how to add binary. The algorithm at the end i messed up. Oh and I wasn't sure about features of the IDE. But most of it was good

I didn't know what to do for Ethical but for Legal I wrote about the Data Protection Act and how she should only hold relevant information about her students and stuff. The algorithm I did a flowchart for so i'm sure I got a couple marks. The features of an IDE is just the compiler and how the 'run' window (I think it's a .exe) hides the source code.

im just grateful i didn't mess up compiler and interpreter

I messed up the interpreter question. I wrote it read/scanned line by line (even though I knew it was wrong) but it was more of a guess to try get a mark.

Im the same as you! I found it REALLY easy, apart from the Binary addition question!

lmao that's correct if you wrote that about the interpreter

Really? I thought that was the Translator.

Yeah generally it was okay, the image and sound question was probably the worst for me, and I messed up the binary addition. The IDE question was actually not too bad? And the 6 mark questions were fine, the algorithm at the end was quite tricky.

an interpreter is a type of translator that translates source code line by line :smile:

Omg.... Am I the only one who found this paper REALLY difficult? :frown:

Interpreter translates line by line and highlights errors...

Compiler compiles whole code so you can see if there are any non syntax errors such as logic errors - however any errors won't be highlighted.
Last question was gay

Wow... Now I feel stupid but happy I wrote it haha!

I think so. But don't worry, there's 1 class at my school in my year doing this of about 26 students and only about 7 of them are smart-ish. If most school are like that the grade boundaries will be low.

Yeah I wrote the compiler does the whole thing and interpreter goes line by line :wink:
Lol am I the only who is generally quite happy 😅

I found the sound question easy. It's literally like two lines. The audio is measured at regular intervals at a chosen bit rate by the user. It is then converted into binary using an Analogue to Digital converter.

Nope lol. I got 44/45 on both controlled assessments so I'm laughing lmao and the paper was easy except the algorithm

I put stuff about encrypting the usernames and sensitive data about the pupils. For ethics I did stuff about monitoring what is transferred to make sure its not inappropriate and monitoring chats to prevent bullying etc. since its kind of like a forum system.
Anyone know the answer to the query criteria question...?
