I might not be doing exceptionally well in methods but I feel like I can still chip in. In my opinion (unless your school's tests are as crazy as mine, where 50% is sometimes considered an above average mark) getting over 50% to around 70% is a matter of knowing the basic concepts really well and being able to do the basic application questions. For me, I learn the basics by first copying down a few examples and trying to understand them. Afterwards I start doing questions related to the topic. Also always check your answers or else you won't learn from doing the questions. Whenever I get a question I don't understand, I copy down the worked solutions and try to understand them. This is my way of learning. So, basically I learn by understanding the method by looking at examples and then doing some questions. This is how I learn, but you might be different, so find your own ideal way of learning.
