Language school that fits for me?

I have been looking for JLPT preparation from next january, for 3 months, I am only able to attend morning classes. Does anybody know one?

I Was a member of ISI ikebukuro, but the morning classes is only for advanced students, and I was in an intermediate class.

I found Coto, they claimed to be the best school, but their prices almost the double of that ISI offered.
