I'm going to share a bit of an insider secret... Character sheets that are customized to your class are hands down the best tool for those that are new to dungeons and dragons. Even if you're a veteran playing a new class, these are a great tool to put in your toolkit. Before any of us can truly sink their teeth into a campaign and Role-play with the best of them it's so soooo important that we have a solid understanding of how our character can interact with the world, other characters, and the DM. You'll hear the rule "know your move before your turn" from any DM worth their salt, and custom sheets give you a leg up on that.
I've included a link to one of my favorite bundles. They're all specific to classes and give plenty of room for equipment and traits. I still recommend having an organized notebook for all of your extras, your backstory, and keeping a log of all your shenanigans.
Best news is that they're free, unless you'd like to donate (you should definitely donate the recommend 4.95, it's worth it for a TON of content). You can use them for years and years, share with friends, and get really comfortable with playing whatever class you want!
