For some physics and most maths subjects in 3rd you year may need Linear Algebra, Calculus 2 and Real Analysis and Applications as prerequisite subjects. Instead of those 3, you could do Accelerated Maths 1 and 2 and still meet the prerequisites for those subjects. So basically the two accelerated maths subjects = Linear Algebra, Calculus 2 and Real Analysis and Applications
so if you want to save a space for a subject that might interest you, or one that you may need for a different subject, then it'd be better to do Accelerated Maths 1 and 2 I guess
and yeah, that's pretty much why I'm doing the accelerated maths subjects instead of doing the other 3
The choices for those who have done UMEP Maths are different.
If you have done UMEP Maths, there is no point doing Accelerated Maths 1 or Linear Algebra because,
UMEP Maths = Accelerated Maths 1 + Linear Algebra
The Handbook makes that pretty clear.
I was having a similar discussion with tram on another thread, regarding options for UMEP students.
For reasons I can well understand, he chose Vector Calculus + Accelerated Maths 2.
I chose Calculus 2 + Engineering Mathematics.
I believe that both of those options (+UMEP) take you as far down the Maths road (if not further) as the Accelerated Maths 1 & 2 combo.
