<p>Yes, you have to pay for the summer semester. Summer classes are $1,360/unit (the price just went up), so a four-unit summer class would cost $5,440 (plus room and board). In Fall or Spring if you take more than 18 units, the extra units cost $1,360 each [Schedule</a> of Classes: Fall 2010: Tuition and Fees](<a href=“http://www.usc.edu/academics/classes/term_20103/tuition_and_fees.html]Schedule”>http://www.usc.edu/academics/classes/term_20103/tuition_and_fees.html)</p>
<p>There is a new Academic Achievement award for students pursuing double majors or major/minor combinations. If you need more than the 18 units/semester to complete both programs of study AND have a USC GPA of 3.75 or more, you may be eligible to take up to 20 units in Fall or Spring semesters without incurring extra cost. [USC</a> Academic Achievement Award | Undergraduate Education](<a href=“http://undergrad.usc.edu/renaissance/achievement_award.html]USC”>http://undergrad.usc.edu/renaissance/achievement_award.html) Summer is not included in the program.</p>
