Little and Often
There are lots of ways to learn, and we all learn in different ways, but it's amazing how much progress you can make by simply breaking your learning down into bite sized pieces. At school we have to follow timetables that suit the administration of lots of students, but once you are in control of your own learning, you can decide when and where. For a change, try just listening to English advertisements on television, or online. These tend to be quite catchy, and can be quite repetitive so there are lots of chances to listen and repeat.
