I wouldn't want a doctor who failed Maths lol.
That's how people get killed when their doctors accidentally prescribe them 100x the intended dosage.
Except that when doing prescriptions, you don't need to use third degree functions, nor logarithmic functions, nor asintotes or holes.
I can do maths. Just not as advanced as the mathematics subject. If I couldn't do stuff with maths, I would've failed laboratory and organic chemistry as well since we have to neutralize, calculate the reactions in moles/liter, etc.
