How do i become a better test taker when it comes to comprehension tests?

i really have trouble on these tests. i still have to maintain having time which makes me not available to taking a lot of notes while reading the text. i just got a 50/90 on my final which made me really want to change the way i do on these tests. as i keep getting closer to taking the act test, i really need on this type of tests, as colleges will look at these exams. attached is a note my teacher gave me.

Ineed it now in this discussion you will use what you learned about the poems "will there really be a 'morning'? ", "i dwell in possibility", and "ozymandias" to compare how both dickinson and shelley used form - lines, capitalization, and punctuation - to bring meaning to the poems. let's check out one of your classmate's posts: in both "will there really be a 'morning'? " and "i dwell in possibility," emily dickinson capitalizes the words in the poem that tell the reader what to focus on in the poem. shelley also capitalizes words that are not names. these must be important to the meaning of the poem. create one post that compares how both dickinson and shelley use form - lines, capitalization, and punctuation - to bring meaning to the poems "will there really be a 'morning'? ", "i dwell in possibility", and "ozymandias".
