Is this a good idea? (Buying stock for stock game)

Today is the last day of the stock game at my school (I need to do well to save my grade)

The stock market opens in around 3.5 hours from when I am writing this post.

Earlier this week (yesterday), I invested in RIOT. I was impressed by how much money I accumulated in one day. I've already sold American Airlines stock (they aren't doing too well as a company as shown by the picture attached below) and will buy more RIOT stocks right once the stock market reopens with the money earned from selling the AAL stock.

Would you recommend basically selling all of the stocks I have right now which are doing poorly in their after hours and pour my money into RIOT? Or should I just keep my stocks the way they are?

I'm impressed by RIOT and think it will get me a lot of money in one day - especially if I invest more - but as I am not as experienced in stocks as some of you on this subreddit, I want to make sure I am not f*cking up. By just looking at RIOT in their after hours, I feel confident that it will be a good day if I invest a ton in their company. They have a strong upward trend and they make great games (I think I might've played one of their games in the past). I appreciate your feedback

Current amount of money I have in the game: $101,453.85 (USD)

Money I'd ideally like to make by the end of today (Friday): + 2 - 3k

One guy in my school made $15k in one day and went from rank 175 to rank 3 in one day so I'm not being too optimistic when I say this is how much I want to make.

I am ranked 155 right now. The number 1 guy has 118k in his account. Getting more than that would be a stretch but like I said getting 2-3k dollars would get me a B and not a C in the game.

EDIT: If needed, I can sell all my stocks and just devote all of my money on RIOT. Please recommend a good course of action
