As we are students in schools,we will touch more and more knowledge everyday.So the big problem is how we can learn it very well.In my opinion,the first thing we should do is to make a clear plan for your studies according to the curriculum schedule.And then you should carry it out strictly,which includes many aspects,such as preparing lessons before a class,keeping a good habit of taking notes,summarizing the key points after a class,and reviewing those points regularly,and so on.Actually,no matter what your major is,as a learner,the most important thing is when you have problems or cannot understand some tips,you should ask your teachers for help or turn to other students firstly.Learning is the process of accumulation,so every step is vital though it seems to be boring in some way.However,you will know its value someday.
