Is it frowned upon to take extra classes before transferring to UT Austin

<p>Currently attending SAC and have 29 credit hours from there/Blinn CC. My question is, is it alright to take a few extra classes to boost your gpa?
Liberal arts admission for UT Austin seems to be 3.3-3.5 ish min.</p>

<p>I am currently enrolled in 12 hours and will add this to my total once I complete them, but don't have a gpa that up to par with UT just yet, is taking an extra semester or two ok to do?
I'm a sophomore currently.</p>

<p>Any help would be appreciated.</p>
