Can someone please look at/correct my complex IF Excel Formula?

I am creating/developing my school's assessment system! Please could any little excel genius help me correct this formula:

= IF(H3="SUR",IF(Subject!C3<2.7,"Not on track",IF(Subject!C3<=3.29,"On track",IF(Subject!C3>=3.3,"Above", IF(H3="MAS",IF(Subject!C3<2.2,"Not on track",IF(Subject!C3<=2.79,"On track",IF(Subject!C3>=2.8,"Above", IF(H3="EXP",IF(Subject!C3<1.7,"Not on track",IF(Subject!C3<=2.29,"On track",IF(Subject!C3>=2.3,"Above",IF(H3="EM3",IF(Subject!C3<1.2,"Not on track",IF(Subject!C3<=1.79,"On track",IF(Subject!C3>=1.8,"Above", IF(H3="EM2",IF(Subject!C3<0.7,"Not on track",IF(Subject!C3<=1.29,"On track",IF(Subject!C3>=1.3,"Above",IF(H3="EM1",IF(Subject!C3<0.23,"Not on track",IF(Subject!C3<=0.42,"On track",IF(Subject!C3>=0.43,"Above"))))))))))))))))))))))))

The result is dependent upon what is entered within H_, and each category has specific ranges. Thank you! A grateful school teacher!
