There are very little programming in the actl courses.
You cover VBA in ACTL1001, the introductory course.
Otherwise, you may use R or SAS in future actl courses...not to any specific depth...you just brush on it really.
Usually, you always deal with Excel. Excel is a useful program.
And to address the other part of your question, actuarial studies isn't all about maths...which is why actuarial science is a separate discpline from maths. Actuarial science has their own notations and own concepts/theories which mathematicians may not understand. Basically, you apply maths to theories of statistic and finance and economics and such. Et cetera....et cetera...
