Like many other posters here, I am interested in pure mathematics and physics who wants to open postgrad school options in engineering. It would be so nice if I can do a double degree in engineering and mathematics or physics, but my school won't allow it due to the heavy course load of their engineering programme. And I don't think I will have an adequate preparation for grad school in mathematics or physics by doing a minor, if I happen to go to grad school in the pure sciences. So I was thinking of overriding into few specialized engineering courses of which I am particulary interested and then pursue a master's degree in that field. But I did some surf on the Internet and it seems like I need a bachelor's degree in engineering to qualify for a P.Eng. designation exam. Is this true? Next question, I am quite certain that I need some credits in accounting courses when applying for CPA exams or such. So can I become a chartered accountant by doing a master's degree in accounting after a bachelor's degree with mathematics? Thank you in advance for any response.
