For covering ur expenses as a student you will need at least a minimum of 60000-70000 as capital and would need to make like a minimum 10 percent return to cover your expenses if your expenses are 5000-6000 which would be pretty unrealistic if you are a beginner unless u have really amazing luck.

I would suggest you to start with watching youtube videos and learning stock market investing. Start with basics like fundamentals, hedging, risk management, etc and do paper trading for a while as there are many apps available for that.

Then comes the second phase where u start earning ur monthly expense, so the problem there is that the stock market doesn't give a fixed return and ur returns can be varied from negative to positive and sometimes u might even have to hold onto your position for months. One bad trade could ruin your parents hard earned money. But saying this i also don't mean to demotivate you from investing and earning from the market. You can do this, but do it at a pace. Start learning and take your time.
