=IF(AND(J43>=45,COUNTIF(J29:J42,">=3")=0),"EE",IF( OR(AND(J43>=45,COUNTIF(J29:J42,"<3")),AND(J43>=36, J43<=44,COUNTIF(J29:J42,">=2")=0)),"AE",IF(OR(AND( J43>=36,J43<=44,COUNTIF(J29:J42,"<2")=5),AND(J43>= 16,J43<=35)),"PA","NA")))
thay bằng
=IF(AND(J43>=45,COUNTIF($J$29:$J$42,"<3")=0),"EE",IF(OR(AND($J$43>=45,COUNTIF($J$29:$J$42,"<3")>=1),AND($J$43>=36,COUNTIF($J$29:$J$42,"<2")=0)),"AE",IF(OR(AND($J$43>=36,COUNTIF($J$29:$J$42,"<2")>=1),$J$43>=16),"PA","NA"))) như trên thì mới đúng
