<p>I would say the difficulty in both engineering department and math department is comparably about the same level. Math is more theory (proofs) based while EE is more applied. However, this is just my opinion… it is rather a subjective opinion!</p>
<p>For actuary exams, you do NOT have to major in a specific program. However, math/statistics majors would better serve you to prepare for the exams. You do NOT have to take any specific courses even though some math courses would definitely help. </p>
<p>For many test takers, I would say majority rely on self-studying. Also, information on practise materials is readily available on the internet. </p>
<p>Just some advices for undergraduates, you should focus in 1 field rather than many fields and choose your field carefully.</p>
