Periyar University

 I think the answer is no because both universities are private university and both are good university as far as curriculum is concerned so both the universities charges almost tge same amount of fees for thier subjects.As far as btech  courses is concerned  periyar University charges 70000 per sem and sastra also acharges 72000 per sem which is not a big difference and devplment fees and hostel fees is almost same approximately 20000 per year .As far MBA is concerned sastra charges 1 Lacs per se. Where periyar charge 80000 per sem  so here periyar is less expensive than sastra university.For other courses you also find  periyar charge less amount than sastra university though the  difference is upto 5000 rs.
