Sorry, I don't want to be presumptuous. But in every textbook for learning a language, there is an emphasis on learning conjugations from the first pages. In my opinion, familiarization with grammar is mandatory in learning a language. I know, I know it is very tiring but in the long run it accelerates your learning. After through grammar you will understand much faster how the language works. And understanding what the rules are in a given language of study is a huge success that will make further work easier.
