What are some good ways to study / pay attention when you struggle with the subject?

Study Tips:
When struggling with a subject I find it fun to either make a song out of the topic or make flash cards. It may sound funny but it works.

Music is something most people believe they can't live without so why not use it to your benefit?

It's simple, you basically find a tune you like and match the topic to the tune of your choice.

Hope this helps!
