Honestly, the evaluation process at Anna University is quite messed up. There is no proper strategy behind their valuation. It’s just your luck that decides your marks.
Most of the students have to apply for revaluation, the fees for which is around INR 700 for a single paper. Apart from this if you are willing to apply for a challenge review, the cost is INR 3000. All this seems like a money making strategy. Despite revaluation students keep getting worse grades every year.
This practice is spoiling the future of so many bright students. Hope someone takes action.
