New to investment: Need Advice.

I am almost 21. I have accumulated a corpus of ₹7 lakh. This is literally all the money I have. I need to grow this money to 9.5 to 10L by 2028 (3 Years) to fund my higher studies. I am thinking of putting the money in parag Parikh flexicap due to its good risk adjusted returns. Should I put all my money in it? Or should I diversify by putting some money into index or debt funds to reduce risks? Or should I try to ride the bullish run of the market by investing half of my money in quant or JM funds that give even better returns? As I am new to it, I am also unable to predict whether the markets will continue rising in 2025 or are there risks of short term crashes. Please guide.
