CRP's main function is pre-flight planning, with a chart. Of course any computing aid or even pencil & paper will do. That's why it lives in my bag.
i.e. Used before, without a care, you fly off in the general direction of 'x'.
As per se it's unknown how good the applicant's trigonometry is, the CRP test presumably demonstrates that one understands the basic 'rules' and thus better knows how to visualise the effects of wind, on drift & velocity.
[Rather than wholly believing a digital read out from some random piece of kit the P1 has decided to use.]
