I need to calculate the percentage increase of learning outcomes comprehension before and after an educational course. How do I measure that increase? Sample data is below.

BEFORE 1 (Low) 2 3 4 5 6 (High) Response
Count
Outcome 1 28.6% (2) 14.3% (1) 28.6% (2) 14.3% (1) 0.0% (0) 14.3% (1) 7
Outcome 2 14.3% (1) 0.0% (0) 42.9% (3) 28.6% (2) 14.3% (1) 0.0% (0) 7
Outcome 3 14.3% (1) 14.3% (1) 28.6% (2) 14.3% (1) 28.6% (2) 0.0% (0) 7

AFTER 1 (Low) 2 3 4 5 6 (High) Response
Count
Outcome 1 0.0% (0) 0.0% (0) 0.0% (0) 28.6% (2) 42.9% (3) 28.6% (2) 7
Outcome 2 0.0% (0) 0.0% (0) 0.0% (0) 28.6% (2) 42.9% (3) 28.6% (2) 7
Outcome 3 0.0% (0) 0.0% (0) 0.0% (0) 28.6% (2) 28.6% (2) 42.9% (3) 7
