A lengthy and structured curriculum is not necessarily the best form of education these days. There are many alternatives to get the most knowledge with the minimal amount of time. Online courses are good for self-study but they do lack the interaction with a real physical presence of people and team-based collaborative project work. Targeted short form face to face courses are available in many locations around the world and they offer part-time weeknights or weekend sessions so that you can still focus on your work while gaining additional knowledge. Courses can range from weeks to 1-2 months to focus on building your skill gaps and get you enough knowledge to move forward as quickly as possible. Requisites are rarely needed, just need to be open-minded and curious to learn.
