You have a good GPA, and I’m sure that you’ve worked very hard to get that so you need to consider some things before settling on taking both classes.

First, how hard did you find Spanish 1? How much of your time did it take? If you found it to be challenging (despite what your final score might indicate) then you can only expect Spanish 2 to be equally as challenging. How much time did you spend working on it? You can expect to double that time if you take another language.

Next, How much are you willing to sacrifice for that extra class? a 3.8 GPA is great, especially with your after school stuff, but another class, especially one as in depth as Chinese (which isn’t even latin based so somewhat similar to English) could have a negative effect on that GPA. Since you’re going to be a junior and probably applying for colleges after this school year you’re going to want to keep that GPA as high as you can.

Hopefully this helps a little bit. I would try making a list of pros and cons to help decide one way or the other, but I don’t think I would take both languages.
