Mainly textbook questions and the SAMs, Specimen material and the 2018 AS exam. Old D1 papers seem to be helpful as well. Wbu?

I heard it was reccomended to use pencil in the old spec for filling out tables but I can't verify it or know if it will apply for this year as well.

I'm going to use a pen - better safe than sorry. Although I'll be bringing in a pencil and a highlighter so that I can annotate onto the question book. You are usually allowed to use pencil for diagrams/ sketches so I don't know if templates count as this.

Just did a practice mock and managed to bag 70/75 marks (couple silly mistakes with a linear programming constraint and a reasoning question). I might just not revise until Sunday night and chill for the next few days

Can you link the mock paper you have done, I would appreciate it very much

Thanks in advance and good luck!!

Anyone else just ran out of steam at this point? Pretty tempted to just pack it up and wing it on the day, such a terrible module to revise for with the diagrams to draw and stuff

I have a question which is going to sound silly but I seem to always struggle with this:

If I have an objective line: y= -3/4 x +3 and it represents profit which I am wishing to maximise how do I convert it into a form of P +/- Ax +/- By = 0

you take y and x to one side
y+3/4 x=3
then times by 4
4y+3x=12
therefore P=4y+3x

Ah okay that does make sense, because the initial line I found is the objective function but not at its starting point, it would be starting at (0,0) and that's why its like this.

Thank you so much!
