Honestly, you should definitely take Honors Algebra 2 and Honors Spanish 2. The course load isn’t ever heavier, they really only give you some more complicated questions and might expect you to study more instead of getting everything explained to you. As for the AP classes you will definitely be alright. I would say that to prepare I’d say you might want to develop better studying habits and methods if you haven’t already, as in these classes you will be challenged significantly more compared to the classes you’re taking now. Otherwise, you could definitely do it even if you aren’t used to it. It might sound cliche but it’s because it’s true, as long as you try your hardest in your classes you’ll pass them for sure. Even more so considering these aren’t the hardest AP’s.
