As with language 1 and how they stated marks to help you; ie with one of the earlier comprehension questions and the use of the superlative: "celerrime" with only 2 other points to make, thus leading to the deduction that an extra word was required in order to obtain full marks. Such, in language 2, I would advise closely looking at the number of points you've made relative to the maximum marks for each question.
As for the comprehension, be wary of words that look alike and tenses that look similar to another form.
