Typical US-deception - much ado about nothing

Many of the US textbooks seem to have one thing in common: little substance. I was really surprised sometimes how to fill 600 pages with much aufblasenen information. This does not mean that I found the book per se bad:

Especially the application suggestions for writing part are very useful, as the schemes for Speaking part.

But one needs for 600 pages? No. This could have been just as well have wrote down 50 pages (no kidding!). A lot of information are repeated twice or three times. Part techniques be learned in order to then ultimately to make yet again different in the actual test chapters. Also, I think in particular the Reading techniques not useful - because for writing and summarize you in TOEFL no time. Some of the information in the book really banal.

What the book lacks: Practice Tests! The best exercises are practice tests. And of the book has only one.

Conclusion: Can you buy, you can read the TOEFL is one that does not make "CRACKING". 1 star deduction for even one star less because I could write loosely ne summary of about 50 pages, without really omit something.
