Not sure if you've sorted this out yet, but last year, this was the situation with Maths for someone in your position:
1. If you want to take the standard route, you do Experimental Design and Data Analysis in Semester 1 and Calculus 2 in Semester 2. A lot of people dislike EDDA, but I think that you do recognise its value since it teaches you a lot of statistics used in medical studies/other scientific papers.
2. If you want to "keep your options open", as far as the bioengineering pathway goes, you do Calculus 2 and Linear Algebra - this is a bit more intense "maths" (though I found Calc 2 pretty straight forward, apparently Linear Algebra matrices are manageable but annoying). You don't do statistics.
3. If you want to "keep your options more open" (in the sense that you could arguably do the Diploma or Informatics as well as bioeng pathway) or you REALLY love maths, you could try and do the accelerated pathway - but the problem with this last year was that its lectures are very intensive (Accel 1 and Accel 2 are effectively three subjects worth of credit). The lecture times clashed with a lot of biomed times so you would have to miss one lecture or the other - maths lectures in general are not recorded on lectopia for play back. I would probably recommend against this choice unless you're really very good at maths - it is a great deal harder than either of the other two options above when you factor in the clashes as well as actual content.
That said, I went for Option 1 - maybe people who have done 2 or 3 could chip in their views!
