Uralya,
I still have to learn how to drive... LOL!
Dear, foreign language really depends on the person. I, for one, love language; it's a passion, really, unless you wind up with a [imprecation] Spanish teacher who only sits at her poorly-organized desk and listens to Pandora and scrolls through her newsfeed. Oh, wait, where was I?
Keep your GPA above 3.0, and you'll be fine (if you're talking college here). If you want to get into a great college, keep it above 3.5. Do lots of community service.
Homework is easy if you properly manage your time.
I am taking AP Biology this year and AP Literature next year. AP classes, I shall assume, are only stressful if you make them stressful. Keep your chin up, and stay organized. Don't procrastinate.
Tests. Well, let's just say that I scored the highest out of the entire Sophomore class in the PSAT. I think I'm a natural at testing, LMAO. I only missed one question on the U.S. History EOCT, which PISSED ME OFF BEYOND END AND I AM STILL PASSIONATELY ANGRY ABOUT THAT.
Really, it all comes down to dedication and time-management. If you can stay motivated and manage your time wisely, then you can do anything.
Best of luck and warmest regards,
Dustin
