I’d say about 10% (24) or so questions require calculations.
Knowing the quant, behind the theory, down pat helps you manipulate variables and see how things correlate. So even though there may not be that much “number crunching” it is nonetheless helpful to know how to do most of it.
Detailed formula’s like Bayes or the Skewness are probably not even worth memorizing. But this is just my advice.
