There are plenty of great places on the web to read up on various aspects of your chart, or just to learn more about astrology and the planets. I avoid the sites with too many blaring pop ups and favor those with higher quality, free reading content like Cosmic Intelligence Agency, and the Astrology Hub.
If you are in the Houston area, you can check out the Houston Astrological Society meet-ups, which organizes free and low-cost lectures on various topics for the public. Their facebook page is HAS Facebook Page.
Chris Brennan does a great free podcast, if you are already well versed in Astrology, but it can be a bit much for beginners.
