I will have the exams at the end of the year, and I have many tests everyach week.

I am pretty intelligent at school so I can haveget good grades with nout working hard but for other people, sometimes it's more complicated.

I am in a really good University (the best in my region in Normandie), and the pupils who have difficulties can feel a pressure made byfrom the teachers or the director.

I know, because, I also do that.

A break is more natural before "because" than after it

For the best pupils, you want to have the best grades ofin your class and when you have difficulties, you want to have a better grade thatn the mediuman.

And I think it's this competition who provide usich pressures us.

You always want to work to get bestter grades thatn your friend.

"best" is used when picking the best amongst several things, for one to one comparisons "better" is used

Nevertheless, I think you can't acting like there areis no competitions, because I think, it's also the thing that will makes you motivated.

Same as before, the pause is more natural before the "because"

To conclude, I think there is a pressionure in schools, ithat's obvious, particularly for the people who don't get good grades.

As a teenager, I go to the school almost every day (6 times a week) because I also work on Saturday.

Personally, I don't feel pressure from them but I know it'sthat it's been a bit difficult for some people.

The end is a little unclear. By "work" here we would assume you have a job at the school. If that's the case, include the "there." But if you are there just for additional school work, maybe say something like, "... because I also have classes on Saturdays."

If you are intelligent, you are intelligent; we wouldn't phrase it that you are specifically intelligent while at school. I should maybe mention that this can sound arrogant, but I'm not here to judge you :)

I am in a really good Uuniversity (the best in my region in Normandiey), and the pupilstudents who have difficulties can feel a pressure made byfrom the teachers or the director.

The word "university" is not capitalized, but if you referenced your specific university by name, that name would be capitalized.

"Pupils" sounds a bit strange to use for adults/older teens in university; it is more appropriate for very young school children.

Personally, I don't feel pressure from them, but I know it's a bit difficult for some people.

However, getting good grades can be difficult, and at the Umy university, there is something weird where all the pupilsa weird thing students do where they compare their grades with thone other.

More natural

I know because, I also do that.

For the best pupilstudents, you want to have the best grades of your class, and when you have difficulties, you want to have a better grade thatn the mediumaverage.

And I think it's this competition who providethat gives us pressure.

Generally, "provide" is going to be used for positive things

You always want to work to get bestter grades thatn your friend.

Nevertheless, I think you cashouldn't acting like there areis no competitions, because I think, it's also the thing that will makes you motivated.

It's not a good idea for you to do it = you shouldn't
It's not possible for you to do it = you can't

To conclude, I think there is a pression inure at schools, i. It's obvious, particularly for the people who don't get good grades.

But, this competition can have some good effects too, like motivating you.
