there are some very useful lectures at Youtube, my personal favourite is " https://www.youtube.com/watch?v=JKF_rGBlLM8 ". It has 22 parts of around 40 minutes if you are commited to learn then these might help. Go through them and let me know whether those are helpful. 

Thanks Adans for your correction!!!
