Spanish years 1 and 2 in high school and Spanish semesters 1 and 2 in college have substantial duplication (assuming level 1 in both cases is for beginners). Depending on the high school and college, completion of Spanish semester 2 in college may be equivalent to completion of Spanish year 2 or 3 in high school.
A student who completed Spanish year 2 in high school should probably place into a college Spanish course higher than semester 1, unless the high school’s Spanish courses are of poor quality or the student did poorly in them.
