Hello. Some of my spokes broke and im trying to fix them but I need to take the cassette off first. I’m new and usually try to do things myself. The bike is a gt aggressor so I’m not to worried since I bought it second hand years ago. What tool would I need to take the cassette off? I’ve been watching park tool videos but I’m not 100%

You will need a cassette tool (splined but that goes in the middle of the cassette) and a chain whip (to keep the freehub from spinning when you turn counter clockwise). The tools will probably cost you more money than the bike shop will charge just to remove the cassette.
Given your scenario I would see what the shop charges to replace spokes. It isn’t really a repair I would recommend for a beginner.
Here is a video that includes all the tools required: [https://youtu.be/SZZdB_P3mmc?t=18](https://youtu.be/SZZdB_P3mmc?t=18)
Essentially you need the chain whip, and in the case of Shimano, any FR5.X park tool
I use a Rockshox topcap/cassette tool with a ratchet and a Pedro’s Vise Whip.
So aside from this repair, you should be using your large chainring (on the crankset) more. This shows that you are spending like 80% of your time in the smallest cogs, which is going to make the cassette and chain wear really fast. The larger the cog/chainring you ride, the slower everything will wear
Are you lugging along in the hardest gear all the time? Spin faster and use your gears.
