Um... I'm not sure if you're trying to ask "Is it a lot of work to correct a sentence?" but if you are, I can tell you that it can be simple or difficult depending on the sentence, language and diction. For example, is it a complete sentence, or a fragment? Are there spelling errors? Does the sentence contain dialogue?
An example sentence (incorrect): The apple, was red with shiny and looked delishus.
First, consider incorrect words: "With" should be "and" in this sentence.
Next, spelling errors: "Delishus" should be "delicious."
Then, incorrect punctuation: The comma after "apple" doesn't belong in the sentence.
People who have studied English and sentence structure, or have talent and/or skill in the area should find correcting improper sentences rather easy, whereas people who have not or do not have talent/skill may find the task difficult.
It's a lot of work. That is a complete sentence. Some teachers prefer that you use another word rather than "a lot." Like, "It's quite a bit of work." or "It's much work."
It's a lot of work. (correct) Don't aggravate you. (incorrect, you should be yourself) You like the movies a lot. (correct) She is smarter than he is. (correct, it is implied 'She is smarter than he is smart.')
Does your brother work in a hospital? is the correct sentence.
Jerry handed the instructions to the boys and me.
The sentence "I have many friends." is a correct sentence. An alternate would be, "I have a lot of friends".
It depends how you use it. If you use it after something it can be correct. But being in a sentence by itself isn't correct.
