Thank you very much for your last corrections. Can you please help me find better words to assess these other paragraph? Thank you very much in advance!

1) You have often strayed from the point. Actually, you have introduced a lot of themes you hadn’t been asked for. Bear also in mind each of your paragraphs must contain a maximum of 10 lines! (Is there a better way to express it?)
2) Your paragraphs are fairly good (very good) as far as the content is concerned though the style (or form?) is not always accurate. Some words are mispelt and the word choice is in a few cases wrong (inadequate?). A sentence does not make sense at all and needs to be reformulated. (?)
You continue misspelling the relative pronoun “which”. Can you please remember once and for all that “which” is a wh-pronoun?
3 ) Avoid jumping from one topic to another without attempting to join them. (How can I express this concept: “ you start dealing with a topic then you go on mentioning another and finally you go back to your previous topic adding more details?) Your paragraphs lack cohesion??
4) Can you suggest to me a good site where I can find ideas on how to summarise mistakes in a paragraph (or better assess paragraphs?)
5) Beowulf is the protagonist of the Anglo-Saxon epic poem with the same name. (is “with” correct”?)
6) In the scene of the battle Beowulf represents the good fighting against pure evil.
7 ) Formulas are very widely used (but not "very" used) in an epic poem.
Latin was spoken/used (are both correct?) as the language of learning.

1) You have frequently deviated from the main point. In fact, you have introduced numerous themes that were not requested. Additionally, it is important to keep in mind that each of your paragraphs should consist of a maximum of 10 lines! (Is there a better way to express this?)

2) Your paragraphs are generally well-written in terms of content, although the style (or form?) is not consistently accurate. Some words are misspelled, and the word choice is sometimes incorrect (inadequate?). Furthermore, there is a sentence that does not make sense at all and needs to be rephrased. (?)

You continue to misspell the relative pronoun "which". Please remember once and for all that "which" is a wh-pronoun.

3) Avoid jumping from one topic to another without attempting to connect them. (How can I express this concept: "you start addressing a topic, then you suddenly mention another one, and finally you return to the previous topic with additional details?) Your paragraphs lack cohesion??

4) Could you suggest a reliable website where I can find ideas on how to summarize mistakes in a paragraph (or better yet, assess paragraphs?)?

5) Beowulf is the protagonist of the Anglo-Saxon epic poem of the same name. (Is "with" correct"?)

6) In the battle scene, Beowulf symbolizes the embodiment of good fighting against pure evil.

7) Formulas are widely utilized in an epic poem. Latin was spoken/used (are both correct?) as the language of education.
