The time it takes to learn Korean depends on your requirements and goals. If your goal is to attempt TOPIK (Test of Proficiency in Korean), it takes at least 4 months and up to a year to achieve TOPIK Level 1 / 2. Without a doubt, it takes longer time if you learn Korean yourself using Korean study sites, Korean Apps, and other self-learning materials. Korean websites and tutorial videos can teach you the 40 Korean alphabetics and its pronouncication, equipping you with the basics.
