well the reasons that i figured out was that:
1. students will try to study more, this will result only to study more and learn less. They'd rather just mug stuff up than just learning it.
2. Studying more they wouldnt have time for co-curricular activities. they have a social life.
3. Student prepares to get an A, and studies to get 90% which is qualified for an A in thhe tenpoint grade system. But when the student finds out that he/she gets a B because the new grading system requires them to get a 93%. he/she will get dissapointed and will want to fight back.

Dont know if all of the point i have in my mind will be correct, why why do you ask me the same question i asked you guys?. Please give me reasons that would help me write my letter to the editor. ( its actually meant to be a persuasive essay in a form of a letter)
