Before you start studying at SHJC, you need to sit Placement Exams in English, Mathematics and Spanish. Depending on which level you are in previous mentioned courses, you will be placed based on your results.
Based on your Placement results, you can be waived from pre-college courses. For example, if you pass the English placement test with a 70% or higher, you will be waived from Pre-College English 1 and Pre-College English 2; you will register for College English 1.
Same concept applies to Math and Spanish.
