For Elementary (BEEd) , Gen.Ed. (40%) & Prof.Ed. (60%).
For Secondary (BSEd), Gen.Ed. (20%), Prof.Ed. (40%), Majorship (40%).

CASE #1 (BEEd) 
Scores: Gen.Ed. = (75/150)*0.4 = 20%
Prof.Ed. = (75/150)*0.6 = 30%
Total Rating - - - - - - - - -> = 50% (failed)

CASE #2 (BSEd)
Scores: Gen.Ed. = (74/150)*0.2 = 9.87%
Prof.Ed. = (145/150)*0.4 = 38.67%
Major = (145/150)*0.4 = 38.67%

Total Rating -- - - - -> = 87.21% (passed)

CASE #3 (BSEd)
Scores: Gen.Ed. = (75/150)*0.2 = 10%
Prof.Ed. = (145/150)*0.4 = 38.67%
Major = (145/150)*0.4 = 38.67%
Total Rating - - - - --> = 87.34% (passed)

CASE #4 (BSEd)
Scores: Gen.Ed. = (113/150)*0.2 = 15%
Prof.Ed. = (113/150)*0.4 = 30%
Major = (113/150)*0.4 = 30%
Total Rating - - - - --> = 75% (passed)

113 po ang target score each area..
pwede naman 90 basta mabawi yung deficit na 23 sa ibang area.. halimbawa, dapat prof.ed. 136.
