Yes you have. The mark scheme just swapped the numbers around and then merged the pass. You did the swapping in your head.

Thanks, I really wish AQA made their own books so we know exactly what the mark scheme/examiner wants and how they want me to present my working out.

So, will I get full marks for it?

And also for Dijkstra's algorithm, do I have to draw the boxes that look like double beds (a shape consisting of two boxes on the top and a larger box below it).

I agree. The current textbook we use is sort of outdated.

Yes, you should get full marks according to the mark scheme.

I just draw a normal square box around it. I don't think they mind as long as you have the right numbers and crossing outs.

Thanks, did your teacher teach you to draw the double bed boxes?

Because, I rather just do it as exactly as the mark scheme says, it's time consuming to draw the double bed boxes.

I don't do the double bed boxes. Just a normal square box around the numbers.

Okay, are you doing D1 this January or have you already done it? Which exam board are you on?
