English textbook

I got 2 English textbok last week.

One is a textbook for the TOEIC training that starts this week.

I will go to the Yokohama training center of my company with this textbook every week.

This textbook is heavier than the textbook of our English school.

Another is a sample textbook of the hearing marathon of ALC.

I got this text book free of charge.
As for this textbook, CD to which the radio drama in Canada and Hollywood's actor interview were recorded was sent together.

I think this textbook to be a little difficult for me.
