Sorry you've not had any responses about this. Are you sure you've posted in the right place? Here's a link to our subject forum which should help get you more responses if you post there.

You can also find the Exam Thread list for A-levels here and GCSE here. :dumbells:

Hey! How did you find the exam?
I found it better than last year, but the people in my class said it was harder. How about you?

It seemed to me as if they tried to make it harder, but I think it was OK. What did you put for the three things wrong with the HTML?

1. Forgot to close the <img> tag with </img>
2. Didn't use "text-align" to align the text
3. Not sure - said didn't use <p> tags for the text?

I did the /img one and text-align but instead said there was no file extension on the picture src. I think the image closing tag is wrong though as according to w3schools it isn't needed.

If we can all try to remember some questions and some answers I could form a markscheme but it won't be perfect

Was the equation: NOT(A.B + B+C) ?

not(a.b) + not(b+c)
My answer was notA and notC but that's wrong. I spoke to my teacher afterwards he said it was not(B+C)

I put not(A) + not(B), oops. Oh well hopefully get some working marks or something!

Thats what I got aswell. I proved it using boolean algebra then checked it using truth tables on extra paper (under a different question number). 99% sure this is right.

Your teacher is wrong. Its NOT(A.B).

NOT(A.B) + NOT(B+C) = NOT(A.B . B+C)

NOT(A.B.B + A.B.C)

NOT (A.B + A.B.C) and the C becomes redundant.

NOT(A.B)

Those who got NOT(A) + NOT(B) have found the equivalent I hope they get the marks.

I remember in the paper they actually wrote "scr" instead of "src", so i pointed this out as one of them though i was unsure as to maybe i had just fabricated src in my head and they were actually right but i checked w3s and scr would be a mistake so im guessing that should be one of them? i also put text align and the thing about <p> for the text.
