an article is never successful in the eyes of a CA. dont mind bit thats a truth. it doesnt matter how hard you try to do a job but even after you succeed in your task, you will not get enough praise from your boss. but there are exception to this..... now coming to your ques., knowledge is never ending my friend. there are many situations in pratical life and you cannot come across all of them. so atleast you should have basic knowledge in all fields that a CA can work. rest depends on how you tackle diff. situations. by word "basic" i dont mean only the beginner level knowledge but such level that you would often come across in your practical life.
