Ah, high school... Enjoy it while you can!

Freshman year was soooooo easy for me!
Junior year is the hardest year of high school for most people, and senior year can be pretty tough if you start slacking off (I got very bad senioritis! haha)

If I were you, I would try to focus on school work as hard as you can right now, especially if you're planning on getting into a good college. If you're having a tough time now, things will only get much harder. 10th is pretty bad, but in 11th grade teachers usually really cram you up with work, classes are tougher, and in 11th grade you also start preparing for college.

I agree with you, school is NOT easy, but it is meant to be a challenge. Teachers are 99.9% of the time always available for you if you need one-on-one help, so don't be afraid to ask for help. I've done it several times before and trust me, it really helps!! Also, ask if there is any extra credit you can do to help raise your grade(s).

Good luck, and don't give up!
