Some people argue that schools are not the only place to receive true education, they refute that there are many places to receive education.
I would make this two separate sentences, or separate it by a semi colon.
However, I have two supporting reasons for why schools are the best place to learn.
I would take out supporting, its unnecessary. Also, I would either change however to a different conjunction, or switch I and However.
Schools can teach many useful skills and schools can give formal education by proven teachers.
"Schools can teach many useful skills and can give formal education by proven teachers." And I would change proven to something different. It doesn't quite make sense in this context.
So, there is no doubt that schools are the best place to receive proper and true education.
Take out "So,"
schools can teach the most important skill to live in society, how to socialize with people.
I would change "school" to "They". Otherwise its redundant
Since students see their friends everyday, they will better know how to make friends and how to socialize with new people.
Take out the second "how to". And change "friends" to something more general like peers or classmates.
Some might argue that students will be able to socialize better in other places, but students can build real friendship and companions in school, encountering similar problems as their peers.
The last part of the sentence doesn't go with the first
They need to solve problems with their peers, they would eventually make friendship and bond between friends which would last for a long time.
This is worded weirdly. Check subject verb agreement
Also, schools provide education regarding diverse subjects, these subjects that students learn would be valuable for them in the coming years for them to have a job that they want.
"Also, schools provide education regarding diverse subjects. These subjects that students learn will be valuable for them in the coming years when they go to find the job that they want."
To illustrate, as a student I learned numerous information.
Add "have" before learned
Schools have taught me how to socialize, motivated me to study and to achieve my utmost.
"Schools have taught me how to socialize, motivated me to study, and to achieve my utmost potential."
Teachers who have studied so hard for the passion to teach students have great amount knowledge.
"Teachers who have studied so hard with a passion to teach students have a great amount knowledge."
There is great difference from formal and informal teachers since, formal teachers study so hard to achieve eligibility to teach students. Whereas informal teachers can just read out letters from books.
"There is a great difference between formal and informal teachers. Formal teachers study hard to achieve eligibility to teach students. Informal teachers can just read out letters from books."
For instance, my brother who is a teacher at an elementary school, he has tried so hard to teach students.
Take out the last part
To sum up, schools can provide students with much of valuable information and schools are proven place where students can learn from knowledgable teachers. In this regard, I strongly believe schools are better place to learn.
change "to sum up" to In conclusion. Take out "of". Add "a" in front of "proven". Add "a" in front of "better".
I think the main problem you have with your essay in punctuation and grammar
