A short introduction to the book: In this book all the grammatical topics from Level A1 to Level B1 are explained in detail. But this book is not just a mere grammar book. This is a complete program for learning German. With the help of this book, it is possible to learn German language individually in an effective way, because in addition to explaining the rules of grammar, other important elements of language learning, such as the necessary vocabulary and how to enlarge vocabulary more easily and fast, have been explained in this book. From this point of view, this book is completely different from other conventional grammar books and is perfectly suited to meet the actual needs of students. This book has the following 6 distinctive features: 
1. Elaborate description of all grammatical topics from Level A1 to Level B1. 

2. A list of about 6000 words from Stufe A1 to Stufe B1 has been added in German-English alphabetical order.

3. These 6000 words are also arranged in English-German alphabetical order. 
4. 
These 6000 words from Stufe A1 to Stufe B1 are marked in different ways, so that it can easily be noticed which words should be learnt first in which level.

5. Words from Level A1 to Level B1 are arranged according to their vowel structure, that means, words that have phonetic and structural similarities, such as "baden, fahren, haben, landen, machen, raten, sagen, tragen" etc., are arranged together here. This sort of arrangement of words is helpful to increase vocabulary quickly and easily. In a conventional grammar book or dictionary, words are not found arranged in this way. From this point of view, this book is completely different from other conventional books and is well suited to meet the actual needs of students. 

6. Description of process of learning words faster and easier with the help of mnemonics. As for example we remember the phrase "aduso" in order to remember 5 following connectors: 
a = aber (but) 
d = denn (because) 
u = und (and) 
s = sondern (but, rather) 
o = oder (or) 

Words from Level A1 to Level B1 are grouped into different groups, if one remembers one word for one group, other words of the group can easily be remembered with the help of that word. This use of mnemonics in learning words cannot be found in any conventional book.
