I think I got something similar in terms of the code - not sure though.

For the logical operations, there were 4 boxes - I got AND OR NOT AND
What did you put for computational methods (parallel and sequential)

i got select (id, description)
from tblname
where id = 'g'
order by (id) i thought it said to order by the id or something haha

also order by automatically means ascending so asc is not needed.

For the question on the back i did so bad. I did something like:

R1 = 0
r2 = 0
r3 = 0

rr1 = r1 + 1
rr2 = r2 + 2
rr3 = r3 + 4

if r5 = 0
print (int(r1*r2*r3))
else
print (int(r5 - 1))

something like that and i know this is defo wrong!

For the logical operations one i think i put:

And
or
not

i think lol wbu?

or or and not

Oh yh I put AND at the end as well haha. How many marks was that?

Posted from TSR Mobile
4 delicious marks. Good job.

or or and not
Some people put that but the majority put AND OR NOT AND because:

How can the first box be OR? It needs to be a value that's larger than or equal to 1 AS WELL AS less than or equal to 5 in order to become a weekday.

And the third box is definitely NOT.

Hahaha thank you. For the truth table thing what did u say for the reason why people use it? I said it's used to find logical errors as they are hard to detect and fix because the error in the code occurred without the program realising it

Oh that was pretty okay.

I just said that sequential models execute line by line, from start to finish, in a linear fashion. Parallel models execute in parallel and simultaneously on multiple processing devices. Parallel models are more productive/efficient/faster than linear models because more than one task is being performed at the same time.

Erm, it didn't ask why a TRACE TABLE is used. It asked the PURPOSE OF THE ALGORITHM. I forgot what I put in as an answer though.

Yh sorry that's what I meant. And loool I always get mixed up with a trace table and truth table

Yup that's what I put, however, I didn't talk about multiprocessing devices

Also for the pseudocode one where you had to change bits of the pseudocode to reach the requirements what did you put? I created a constant variable and made two other variables called Area and Area2 and set them to 0. I added an input as well cos we want it to work with every number

Well, either way tbh, I don't think you'll get the mark because I don't think finding logical errors had to do with the algorithm. Sorry

I just checked the internet and on various sites it says that I got it correct lol

Oh really? Well done man. Sorry for reducing your confidence.

Hahaha no it's fine Also for the codes do you think I got like nearly full marks for them or even full marks?

I would say full marks IMO. They seem like they covered everything.

Oh hopefully! I really want that A* hahaha. I really need someone to create an unofficial mark scheme but it seems like barely anyone does edexcel computer science!

17. What did you guys get for the trace table question? I think i did it right but Im not quite sure

Yeah, last year only about 540 people in the entire country did edexcel computer science :/

I got like 1, 2, 4 and 5? Then 2, 3... Something like that? Not sure. What did you get?
