According to documentation mysql_doc; you can use you can use the other syntax of case for what you wanted.

case
 WHEN FIND_IN_SET(edu, "1,1st,2,2nd,3,3rd,4,4th,5,5th,pri,primary,primery") THEN
  SET memEdu = "Primary";
 WHEN FIND_IN_SET(edu, "intermediate,inter,f.a,fa,fac,f.a.c,f.sc,fsc,1rd year,2rd year,3rd year") THEN
  SET memEdu = "Intermediate";
End case;
