SKip mandatory subject problem

In Japan there is one problem about high-school education recently that some school allow students to skip some mandatory subject for graduation that is not necessary for entrance exam.At first it was found only in one school,but it was disclosed that many schools all over Japan had same problem.Now schools are required their urgent corrective action.In this case,the most miserable victims are students themselves who are forced to learn in haste though next year's entrance exam will be held near the beginning of next year.My Alma mater must have had the same problem because we didn't have the subject such like engineering which in longer perspective caused disadvantage after I started working as an engineer.
