I wanna make some money next week

So, I'm 18, almost at the end of highschool. I wanna buy strikes on Robinhood in class (I have to hide my phone tho) Next week I was hoping to make some money because NVDA earnings are coming out. Idk how the market will move on May 18th to 20th, before NVDA earnings and after. I was hoping to buy some calls before earnings on NVDA and or QQQ because I think it will go up before earnings because of the drop on Friday (as seen in the picture above) And after earnings, on Thursday I wanna buy a call or put on NVDA and or QQQ. I only have about $450 to work with. I started with 100 2 weeks ago and I went up to 600, and lost a couple and I'm back down to $450 only doing options. Any recommendations or things to look out for is appreciated! Also I'm in the US and I buy strikes on Robinhood
