Well...Korean grammar is different from many other languages',so you should pay attention to that...and second of all,Korean characters are different,too..they are not Latin letters,so it's a little important to remember them,,but don't worry,Korean is not a difficult language,and if you have good mastery of Japanese,then it'd be easier for you to learn Korean,they're similar in some ways

I am also a beginner but have started to go through some lessons at talktomeinkorean.com. So far i really like it! Both audio and summary in text. There is a lot of lessons available...
