Still a beginner.
Well, if I may be so bold, learning verb conjugations might be interesting but it probably isn't the best way to improve your ability to communicate in Polish. Firstly, you won't use all the verb forms to the same degree - you'll probably use the first person singular far more often than the third person plural and I wouldn't be surprised if a lot of verbs exist more frequently in the passive (like in English). Secondly, Poles themselves often don't pronounce them properly (e instead of ę for example).
Work more on natural communicaive situations and get someone to correct your grammar as you go. You'll see much faster results. Save the heavy grammar work for later.
Then again, if you like studying grammar then go ahead - sorry for spouting off ;)
