Good TOEFL Book

I’m looking for a good TOEFL book that has pratice exams as well as tips and tools for my mother to learn from. Any recommendations?

TOEFL listening lectures: A lecture from a social sciences class (2)

Check the Princeton Official Guide for TOEFL, its a good read and very well explained the basic principles and strategies for all 4 sections

Thanks I will try out your tip. I think Amazon has it for a good price and it would really help us out!
