The D modules

Misleading title :tongue:
But i see that many students dont do too well in Decision modules, why is this?
What do i have to get right? Which parts of D1 and D2 should i spend more time on?

Thanks!
I think it's just because they're the most different modules from the maths people are typically used to before entering the A Level course.

Did you do the D modules?

I did both D1 and D2, although that was about 6 years ago now.

You need a stroppy teacher who will insist that you apply algorithms properly and moan at you until you do. Then you will do well in Decision modules.

Apply algorithms properly?
What is meant by that?
Could you give an example of applying an algorithm incorrectly countered by applying algorithm correctly please?

Thanks!

In both modules the books and the mark schemes show exact layouts and many people simply do not write down all that is required

Not really , no. A case in point is Dijkstra's algorithm, where students often deal with the vertices in the wrong order and so either miss out some of the working values or get them in the wrong order. They will often get the final answer correct then don't understand why they got very few marks,
