whats the point of filling in the circles completely?

<p>my method of filling it out is to
dot them
then fill them all out at the end
to save time</p>

<p>ironically, i was pressed for time today</p>

<p>so i mightve overlooked 20-24 because i saw that the 2 columns were already completely bubbled in</p>

<p>im not sure tho, so what happens if u dont fill the bubbles in all the way?</p>

<p>the dot is pretty big, its more like a filled in circle within the circle
does anyone want to give me peace of mind?</p>

<p>also, i dont remember filling in a question
even though when i went back to look, there answer space wasnt blank</p>

<p>so i mightve filled it out incorrectly
and as a result, everything was shifted up one?
is it likely?</p>
