This Year's Freshman!
You are all Freshman this year which means you have passed 8th grade. Freshman year is a hard year. There is no point in lying. Some things are easier than others though depending on what you like or are interested in.
The most important thing is that you have to do your work. I slacked off a little from time to time and I still have good grades, but I could be doing better if I stayed doing all my homework. I am not telling you to do your homework once in a while because it might cost you some grade points and that could be the difference from passing and failing.
Those are some of the bad things along with a few others because if you don't stay on top of your work, you will get behind, there is no doubt. Freshman year is not like Jr. High; the teachers don't help you to get your work. You have to go to that teacher and ask them yourself.
There are some good things in your Freshman year, but in my opinion there is more bad things. I have already told you about the bad things, but some good things are is a bigger talent show. If you choose some minor classes instead of all major classes you will have a lot more fun. Plus, it is not as much work as a major class and it is also a lot more fun. Intro to Tech is a good example. Making things in woodshop, its a good skill to have and its not as serious as regular, boring, major classes.
Your first year in High School is tough, but if you do the things you like and have fun in school, then it shouldn't be much of a problem, but in order to do well you have to apply yourself and your skills to get through the year.
