About this calculator
College guideline: 2-3 hours study per credit hour per week, plus the class hours themselves. 15 credits = ~37-45 hours per week of school work. STEM and graduate courses skew higher (3-4 hours/credit study). Less than 1.5 hrs/credit usually means you're skating; over 4 hrs/credit means struggling — seek tutoring or reduce load.
Frequently asked

Online courses same?+
Yes — same Carnegie Unit. Online may feel different but credit-hour expectations same.
Less time = bad grade?+
Generally yes, with high variance. Some students learn fast. Track grade trends + adjust.
Working full-time + class?+
Carry 6-9 credits max. 15 credits + 40 hr work = 75-85 hrs/wk. Burnout territory.
