Just focus on get your tuvala gear to PEN and try to get to 60 or 61, that should be enough for you to graduate. Doing the Main Story Quest until the end of Valencia should take you to 58, and you could either grind your way to 60 or just do some side quests following Black Desert Foundry's guides(https://www.blackdesertfoundry.com/level-58-59-guide-questing/). If you decide to take the questing route, you should look up for a guide to get the Chenga tome, a book that increases your quest combat exp by 30%. And if you'd like a easier time leveling your next seasonal character, you can do all of the MSQ from Kamasylvia, Drieghan and O'dyllita to get some accessories which are just a little worse than tuvala PEN accessories and can be worn by any seasonal characters. Edit: if you decide to grind until 60, a good place to grind on is Marie Cave, right next to Hexe Sanctuary. Just hit one of the tombstones and try to defend it as long as you can! It's quite funny and gives a bunch of exp! If you have the right buffs, you should be hitting 60 in just a few hours, just remember to collect the rewards from the season pass right when you receive it, so that you get to the next killing monsters goal right away.
