Hope this helps

Beyond helpfull , Thank you for sharing that with us, I feel so much better about my exam now. Mind at ease

I swear i as freaking out after it because someone said something different and i started panicking, no problem

You are exactly on the same lines as me its unbelievable, except for the first question which I messed up . The rest seems all good though for us both.

Yay! I counted up my marks and i may have got 115/140 which im chuffed at and i've got over 50 marks for the practical (she never told me!! ) so hopefully all goes well :\

Same here , I got a decent enough mark for my coursework and the exam went really well for me so I'm just hoping that I have managed an A . Is that what you are aiming for ?

Yeah, hopefully, cause i want to do Advanced Higher :\ EXAMS ARE FINISHED ! (for this year)

Advanced higher , sounds more fun than the higher from what I have heard . Time to relax though lol because the stress of exams are gone

ei) Even number of mistakes not spotted - dunno if thats correct

If that was a question about a limitation of parity bits, then yes.

My answers are:
1)1023
2) Mips-How many millions of instructions can be processed per second
3a) Buffer stores it in main memory and spooler is stored in backing storage
b) Voltage Conversion and Status signals
4a)Boot-sector
b) Delivery and watching
5) WNIC
6a) bitmap is compressed and vector may have complex attributes
bi)16.7 million
ii)Increases file size
7a)Software specification
b) Revisits earlier stages in light of new information
8a) The order the program must be designed in
b) Written in english so mistakes can easily be spotted
Easily turned into coding
9) A variable with only two outcomes
10a)Given to people to test
b)Meaningful variable names
c) never got
11a) & (but i found out you had to put concatanation)
b) Integer
12a) Scripting
b) Increases productivity and less chance of human error

from that - see a few different answers than me, ... but one that im sure is wrong is 11b) it has to be string... as concatenation is putting two stringvalues together,

your school should/will automatically do the appeal for you.. each department handles their own appeals.. and you dont really need to be anything to do with it, except from asking if they put forward the appeal..

All appeals do NOT get accepted by the SQA.. as it is not only prelim results but also needs more supporting proof - eg. Class Assesments, coursework etc.

Dean

Are you sure?

Varible3 = varible1 (?) varible2


I thought it was "&" and the operation was concatenation as the 8 and the 4 where joined together to make 84. Am I correct in saying this ? No strings where extracted only joined together by concatenation ?

Please correct me if I am wrong.
