Prepearation for nthe Next sSeason

My first season of high school was finished in 2024. I learned and felt lot of things through thisout last year.

By “season” maybe you mean year? Or semester? In English we don’t use the word “season” to refer to the school calendar.

THowever, there awere many more problems more than I thinkexpected.

Use “However…” to show contrast.
Everything should be in past tense if you are talking about 2024 (last year)

AndFor example, there awere many people who awere good at soccer.w When I was playing in the middle school level, I was one of the best players in my age group.

You can use “For example…” to smoothly transition from your previous sentence into this first one.
Again, the first sentence should be changed to past tense since you are referring to last year.

This was because of my good physical. strength. But in the high school level, I must not rely on my good physical.I c strength. I should grow upmy skills by doing hard training.

It’s incorrect to start sentences with the word “because”
“Physical” is usually used as an adjective, not a noun
“Grow up” is mostly used when talking about age. You can say “grow my skills” instead.

I met a new partner.

And iIt was difficult to get close with my new partner at first.

It’s incorrect to start sentences with “and”
Adding “…at first.” at the end sounds more natural.

As time goeswent on we get close very much.Andot very close. But we fight a lot. I should prepare for next syeason withr by adopting a better mentality.

To show contrast between your first and second sentence, you can use “But…”
Again, using “season” sounds strange.

supplementI’ll identify my weaknesses and triedy to makeget better results.

Not sure what you mean by “supplement,” this word doesn’t make sense in this context.

Prepearation for next seasonterm

Season isn't really used for educational periods. Term is usually used for schools for children, while semester is usually used for colleges and universities (but either term can be used for either type of school)

My first seasonterm of high school was finished in 2024. I learned and felt a lot of things throughout this year.

There are many more problems more than I thinkought.

And there are many people who are good at soccer.w When I was playing inat middle school level, I was one of the best players in my age group because of my good physical ability.

because of my good physical.But in high school level, I must not rely on my good physical. ability only. I could grow upimprove by doing hard training.

Starting a sentence with because doesn't work like. You could say "I had a a good physical ability. Because of that, I was one of the best players in my age group". But if you have the "because <reason>" it sounds much better as part of the previous sentence.

"grow up" is much more about aging than other types of development, so "improve" is better here.

I met a new partner.

And iIt was difficult to get close with that new partner.

As time goes on we're get close very much.Andting much closer. However, we fight a lot. I should prepare for next season with better mentality.

Because "we fight a lot" is sort of contrasting with "we're getting much closer", it's better to use a contrasting word like "However" here.

supplementI should improve on my weaknesses and triedy to make better result

I'm not fully sure what time period you intended to refer to here, but assuming it's a forward looking statement, this should also take should.
