You shouldn’t change the amount of tuition unless you’ve made a mistake entering in your T2202A amounts or you your Notice Of Assessment has a different amount for your tuition from previous years. If you change the amount, you’ll have to come back and adjust your return (and any future returns) if you want to recover the amount you took out.

Also, the tuition credit is non-refundable. You only get the credit if you have tax payable. It will not add to a refund. So if you are already getting a refund, reducing your tuition is not going to change anything.

@Jcrao As I said above, you can’t get a refund from a tuition credit. So if you are getting a refund, it’s not going to be the same amount as you had on your T2202, because that’s not where the refund is coming from.
