It's easy to see why the German Grammar (Quickstudy: Academic) is the "World's #1 Academic Outline," as it is a very good resource for German learners.

Here is what I think after my first few months of working with this guide, a few Vorteile (advantages) and Nachteile (disadvantages).

Vorteile:

1. The "Nouns" section gives guidelines for the groupings of nouns by suffix, topic (seasons, months, days of the week, etc.)
2. The clear layout makes each section easy to read and for their length, each section is surprisingly in-depth. I find this a sign of quality. Descriptions are concise and effective.
3. It's 4 full pages of help in understanding German grammar, laminated and pre-hole-punched for a 3-ring binder. It will last!

Nachteile:

1. While all the information is there, it could be even better if the section "Declension of Adjectives" used only one row (not two) for each case. It's a bit hard to read, but it is a small font size.
2. The pronunciation description, especially of the umlaut letters ä, ö, and ü, seems more confusing than anything, perhaps because I prefer to use the International Phonetic Alphabet.

In sum:

This is a great resource for German learners and well worth the price. It's a helpful guide in addition to your books and audio CDs, especially since it serves as a quick reference and at 4 pages, it really gives you a lot of information for a low price.

I'll give it 4/5 stars.
