There is plenty of accountant out there : accounts exec, accounts officer, assitant accountant,..... Any tom,d*** or harry can become one as long as they understand debit & credit.
Chartered accountant will be lesser.
They need to be certified under a professional body, namely MIA in Malaysia.
To do that, you can :
1) Study degree for 4 years, work for 3 years minimum to 5 to 6 years since MIA can easily extend your experience recognition if they felt you are not working enough. Then take MIA exam for around 1 year. Then you become a certified accountant.

2) Take ACCA for 3 years, work for 3 years (if work with platinum employers like Big4 & MNC) its 3 years but with other companies may take more that cos a lot of performance achievement to met. Then ACCA recognise you and MIA will also recognise you and the same time since ACCA is more prestigious. Can become chartered accountant around age 24 or 25.

Maybe parents and most people that have not "worked" in commercial world will tell you degree is the most important but it is not that case in accounting, especially accounting. Technically I think you have misuderstood acca for accounting. ACCA comprised of other areas but accounting is just the core. Got other areas as well.

If your main concern is job opportunities, then my advice to you is:
1) Since you have nothing to do until SPM result, buy all the newpapers you can find everyday.
2) Check the column for job ads.
3) Check for requirement for financial related jobs.
4) You will probably see the line of "Minimum degree or professional qualification" sometimes just prof qual.
5) That is referring to acca,cima or icaew, or cpa,......
6) Then maybe you will see something like "Preferred working experience in Big4" or something.

If you want to graduate before everyone else and work like a whore in  a big company, why not choose ACCA . Straight passport to misery. I will prefer degree if I had known.

And if you dont mind working until this hour everyday, then welcome to my world

Technically manager dont need any qualification. Any tom d*** and harry can become one as long as you know how to manage people. Why not take degree in management or MBA, I am sure there are plenty of college or university offering such courses. Why bother doing mundane subjects like accounting right ? Managers earn much much more too.
