It all comes down to your decision. But then i think you should think more about the type of job you wanna do after uni, and think from the employer's perspective, if they would value commerce with economics major or economics degree itself. What i believe is that most employers would believe...
Let's assume one organisation has a credit average requirement. What are the chances that a person with a credit will get in compared to those with distinction / HD. Does it lean more towards the grades or ECs? Generally what do you think the median grade is for those programs?
Sorry to hear that. But I believe that is how it's done. In fact when a person from BoS came to our school, she told us about the need to put in the preference asap.
Hey what school do you go to? Or around what school rank is it upto? Because if you want 97+ ATAR with a school rank of 200-. You really need to be in that top 1-2 spots for every subject.
