I personally find grammar the hardest part of any language and it is probably the biggest factor in most people's speed of learning, in that if you do not understand the grammar, however good you may be at everything else, your sentance does not make sense. This is the case with most slavonic languages (and germanic I may add), and putting the wrong case ending or the wrong word order may destroy any meaning in the sentance. This book seeks to make that easier, and it does. As I went through it, I felt as if I was reading a good, clear instruction booklet. Actually you'll probably find that learning grammar through this book is easier than trying to make sense of a DIY book or a computer manual.
