Integrated Science Frequently Asked Questions Courses in the major cannot be taken credit/no credit. One pre-requisite for SCI 319, 336, or 495 may be taken concurrently with instructor permission. At the beginning of each semester students will receive an email with a deadline for submitting the Major Advisor Recommendation Form. This needs to be completed at the beginning of the semester of application to the COE. It is recommended that students take PHY 201 before PHY 200. SCI 336 is only offered fall and spring semesters. SCI 336 counts as an SWS course. Do not take the MTTC before you are ready. Taking the test multiple times results in lower pass rates for the program which can influence accreditation and thus program standing for you and your classmates.
