Can a CA student earn more

Yes..................

Depends on the person. In my prev co. I had a colleague who hadn't cleared his final but is earning much more than what you've mentioned. Of course his soft skills and other aspects are good.

IN my point of view

first of all i would like to say  that there is no need to be a CA to earn more money

it depends on person to person that how he managed all things

YES a ca can earn mony more than a normal person

but its not a universal

Depends on the person.

Well, I have seen illetarate people earn more than that and CAs not earning 50k a month. So, there are no rules.
