BUS MAN and Further are completing different.
In my opinion, BUS MAN requires an individual that is able to memorise quite well, be able to apply knowledge in the study design to case study material but often, students who achieve high study scores have a somewhat advanced way of writing and structuring answers.
I would suggest you undertake BUS MAN if your willing to consistently complete practice questions to hand in each lesson to ensure that you can answer any question that comes your way.
IF YOUR GOOD AT WROTE LEARNING FROM A TEXTBOOK, be prepared to receive mediocre scores in next years sacs and exam if you undertake BUS MAN. BUT, if you are advanced in "reading between the lines" and using past knowledge to interpret information, I highly suggest you choose BUS MAN
If your math's abilities are advanced, I would advise you to focus on your strengths rather than the fierce comp.
I WISH u the best of luck!
