Visit a language learning website. Burmese is not the most common language to learn, and because of that many websites dedicated to language learning may not have a link for learning Burmese. Phrasebase.com does have a section dedicated to Burmese.
Explore websites to help you with your reading and writing in Burmese. Sites such as seasite.niu.edu/burmese/language.htm are free and promote literacy in Burmese. Because these are sites based out of a university, they are more in sync with what a language learner needs.
Join a Burmese chat site. A site such as mylanguageexchange.com/Learn/burmese.asp makes it possible to practice speaking Burmese, which not only helps you with retention, but gives a practical application to your other language learning efforts.
