自修工商管理課程是否無可能？

絕對有可能!!!!

你可以先報一 d 文憑課程, 再繼而升讀高級文憑或學位課程.

其實工商管理課程話難又唔係好難 ge, 有心一定讀到. 而且, 而家方間都有好多 le d 課程, 時期仲可以o係好短 ga tim... 有 d 8 個月就可以完成高級文憑 ga la.

當然, 要睇下你有冇咁 ge 時間同心去讀 la~~ 不過睇你有"女承父業" 咁大 ge 去向.. 你一定會成功 ge!!!! 加油!!

If you want to study Business Management by yourself. You can go to public library to borrow Management textbook and study at home.
If you want to learn more and faster, go to university to study part time Business Management course. You can learn managment from your classmate during group discussion and group project. Teacher will teach you management theory.
Of course, you can learn management from the daily work but you must walk many wrong road before do the right things.
Final, no any management theory is true forever, it is subject to case by case
Hope can help you la
