Frequently Asked Questions
How many questions are on a real CSAT Science Inquiry subject?
Each selected Science Inquiry subject has 20 questions and 30 minutes on the real CSAT. This practice bank intentionally contains 100 original questions for broader review.
Which CSAT science subjects are available?
KICE lists Physics I, Chemistry I, Life Science I, Earth Science I, Physics II, Chemistry II, Life Science II, and Earth Science II as Science Inquiry subjects.
Can candidates take more than one Science Inquiry subject?
Candidates choosing Social/Science Inquiry may select up to two subjects from the combined 17-subject Social/Science Inquiry list. A student may select two science subjects, one science and one social subject, or fewer subjects depending on admission needs.
Is CSAT Science pass/fail?
No. Science Inquiry has no universal pass/fail cutoff. KICE reports Inquiry subjects using standard score, percentile, and grade for university admission use.
Is this practice format identical to the real CSAT?
No. The real Science Inquiry subjects use official five-choice multiple-choice items. This local bank uses four-option questions because that is the practice-bank format.
Does this bank copy official KICE questions?
No. The questions are original and aligned to the official science subject structure and reasoning skills; official released KICE materials remain copyrighted.
