Welcome!
I am new here and I am happy there's such a good forum here.
Congratulations.
I read some posts here and I hope you would help me learn interpret my chart.
I would like to learn chart interpretation on my own but I don't know how to do it.
I found some astrology courses but they are either weak or very expensive.
I found a very good astrology course Avalon College. Do you recommend it?
I am from Poland where there are no good astrology online lessons and my English is not very good but I hope I can understand well.
I know the positions of my planets and aspects but I can't combine all my knowledge, I can't put all the facts together.
I have problems especially with aspects. I don't know which are important and why.  
How do I start interpreting a birth chart? I start with general issues like here http://www.astrologyweekly.com/learn-astrology/astrology-lessons.php
Then I try to begin with ascendant and then the ruler of ascendant, but how to put it together?
But then I am lost what to do and what to pay attention to.
Some of the aspects do not match and I don't know which are not important.

Please give some advice how to interpret it and maybe you know any good astrology courses which are free?

Register in www.astro.com and get your chart first! Then use the info on that site to help you! ;)

I know the basics but I would like to get further...

Any suggestions?
It's not such a simple puzzle to get through.

It's not free, but I have found a great book to help figure out where to start with chart interpretation. Its especially helpful in figuring out which points of a chart are of most importance. The book is The Art of Chart Interpretation by Tracy Marks. I dont know how hard it will be to find it in Poland, though. This website also has great interpretations of everything: http://www.geocities.com/rbltre/astro/mainindex.html?200715

I hope you can find the help you need!
