A-Level Computer Science Study Group 2025-26

Hello I'm doing OCR computer science. I enjoy coding and that's why I chose the subject

Hello all of my fellow computer scientists!
I am with the OCR exam board.
I enjoy the logical thinking and technicality of computer science the most, esp. the coding
I probably struggle with Boolean algebra a d things like De Morgan's laws the most.
I chose to study it BC I did it at GCSE and had a real passion for it!

I did it at gcse too. I got 1 mark off a 9😢

What do you even struggle with in regards to Boolean algebra? I don't really find it that large a topic to begin with in the A-Level specification.

Used to be Python but now C

Some of De Morgan's laws, things like that.

That's just NOT (A AND B) = NOT A OR NOT B and NOT (A OR B) = NOT A AND NOT B, in terms of what OCR A-Level Computer Science with concerned with.
You could try visualising them with truth tables.

True, but it's more of the association, distribution and commutative rules. I understand the rules but when it comes to questions I just have no idea which to use

Association: the associativity of the AND operator means that parentheses for a chain of AND expressions are irrelevant. I don't really think there's much to this.
Commutation: AND/OR/XOR are commutative and thus the order of operations do not matter. The add and multiply operators in ordinary maths are commutative, because 3 + 5 and 5 + 3 both equal 8, and 3 * 5 and 5 * 3 both equal 15.
Distribution: I think it would be better to think of this as expanding brackets. Like how x(1 + x) is x + x², A AND (B OR C) is the same as (A AND B) OR (A AND C), or A OR (B AND C) is the same as (A OR B) AND (A AND C). You're just taking out a common factor.
Although, I appreciate that these are more mathematical in nature.

Just saying hi so I can find this thread at a later date if needed!

I am fascinated with how varied CS is - modelling of new pharmaceuticals, financial mapping, quantum computing, robotics, embedded systems etc, Computing is everywhere!
I don't struggle with anything atm... ask me mid NEA 🤣
I'm aiming for CS or Maths & CS at Uni. I loved the subject at GCSE, and was top of my year so it was a natural choice for me.

I loved it at GCSE too, which was why it was my top choice!! What are you thinking about for your NEA?
