How Hard Is It to Learn Czech?

What can really be difficult to grasp as a beginner Czech learner, are the more than a dozen different models Czech uses in its declension. Since Czech has seven cases, that, combined with the singular and plural forms, means that you would have to memorise fourteen different forms of one single word. Granted, this is a difficult task and, to make things worse, even when you learn the entire vast table of different declension patterns, you will not be able to always correctly assess which model a specific word uses just by looking at it.
