1. I will try to be the first in score in my class.
Better: "I will try to get the best score in my class."
2. I will try to get good grades on the exams.
Good!
3. I will try to make a speech in front of my classmates.
Change "make" to "give" and it'll be fine.
4. I will try to eat healthy food every day.
To be accurate, it'd be better yo say "to eat healthful food" -- since I've never seen any food that has an illness!
5. I will try to go abroad to study linguistics.
Good!
