Max number of credits w/o going over? (for registration)

<p>what is the max number of credits I can register for at the UW? I don't remember if it was 18 or 20.. Could someone clear it up for me? thanks.</p>

<p>It’s 18 without having to pay extra tuition. I think it’s around $270 per extra credit on your schedule after 18 credits.</p>

<p>The max … I heard is 30 (for graduate students). I have friends currently taking 21 - 23 credits though, so you can definitely take more than 20 as an undergrad.</p>
