Hello everyone

I was wondering if anyone could recommend / direct me to where I can find science and literature & language arts coursebooks for middle and high schools (Ameircan curriculum) studying at a bilingual international school.The course books should have soft and hard copies, teachers guide/book, test / assessment pack as well as supplementary materials.

We are currently using Holt series, but it's not that easy getting teachers books and assessment/ test pack or other supplementary materials.

Your input/suggestions will be highly appreciated.

Thanks and have a great day!

Tom
