How hard is it to get into a local uni business or accountancy intake? This is the most recent 10th Percentile to 90th Percentile range:

NUS Accountancy - AAA/A to AAA/A, 3.89 to 3.98
NUS Business - AAA/C to AAA/A, 3.85 to 3.98

NTU Accountancy - AAB/B to AAA/A, 3.80 to 3.97
NTU Business - AAB/C to AAA/A, 3.81 to 3.97

SMU Accountancy - AAB/B to AAA/A, 3.72 to 3.96
SMU Business - ABB/C to AAA/A, 3.72 to 3.94

Do you understand what this means?

Extrapolating from this, a 3rd class honours from a local uni biz/acc graduate typically scored ABB/C or 3.72 for their A levels or poly. The level of academic intelligence is that high.

The 10th Percentile to 90th Percentile. These are your competitors for mid end finance jobs, such as analyst positions that you mention. First class hons from science and engineering are also trying (and mostly failing) to get an analyst position.

For your lower end finance jobs like private banking and operations, you have your choice of first class/2nd upper SIM graduates depending on how low you want to pay.

For the upper end finance jobs that just about everyone wants, your competitors are those with double degrees - and got first class hons in both of them. Other fancy stuff include integrated Masters, CFA, overseas internships.

By the law of statistics, getting straight As for your A levels is now the norm. Your differentiating factor is actually the number of As. Do you have 7 As, 8 As, or 12 As?

In such a level of competition, you actually see very good candidates being forced into lower level jobs.
