***** NOT A TEACHER *****
Hello, Mr. G.:
Someone will soon check your sentences.
I just wanted to comment on your use of commas.
In my (very) humble opinion:
In sentence 2, there should be no comma after "differently." Teachers, I believe, call that a comma splice/fault. You have written two sentences. So you need to end the first sentence with a period, or you can join the two sentences by adding the word "and" after the comma.
In sentence 4, there is no need for a comma. "It is an experience and a chance."
In sentence 5, there is no need for a comma. You want to do two things: to graduate and (to) find a good job.
