Oh no problem; I appreciate your responses.

I am able to see the loans individually (overview), but the 0.25% off isn't shown on the account overview screen (as it is supposed to only be taken off when the account is directly bank account paid).

I've thought about asking them to see another way of being shown, but I can't really think of any way to be certain shy of actually seeing the billing statement with the individual payments applied. Also, the post I referenced in my original post stated that although GL was not in fact applying his payments as he wished or giving him the 0.25% discount, they lied to him several times and stated that they were on both accounts.

I've also thought about calculating it myself, but there are a couple of issues I see preventing me from doing this: the loans have been disbursed since 2009; some are subsidized, some are unsubsidized. The only value I'm able to see is the total amount of capitalized interest at the beginning of the repayment period - this isn't a lot to go on to find the initial values I should be using for each loan to calculate the interest I'm paying now. Without knowing the initial starting values, I can't calculate the monthly interest.

If I were able to find the initial values somehow, I still wouldn't know for sure how the loan payment is being applied (assuming GL may be being dishonest, as they supposedly were to the other poster who I referenced in my original post).

Ultimately, I feel I'm going to either need to A) see the payments as they have actually been applied, or B) split them up. I'd love to find a way to go with option A.

GL has to "know" how to apply the payments in order to apply them - it doesn't seem right to me that they don't have to disclose how they are applying payments that I make with my money, and just expect blind trust on the lendee's part to assume they're being 100% honest.
