If you are finding it difficult to make time to study with all of your other responsibilities, you might find that studying while you do other things is a good way to maximize your time and use a more kinesthetic learning approach. Do you need to wash dishes every night after dinner?
Why not put some notes above the sink so you can study at the same time?
Is your phone usually on your desk while working? Tape some notes to the back of it.
Do you spend 10+ minutes in the bathroom mirror every day while getting ready for work? Tape some notes there.
While the people you share your living space with might not appreciate the new decor, all of this extra study time adds up to help you pass the IELTS Exam!
