First, identify your study habits. Make an assessment whether they are effective or not.
For example, your effective study habits are
õ Taking down notes while reading your modules
õ Reading your books for 3 hours
õ Studying with your friends through a group call
If these are effective, then maintain the habit. See to it that you stick to your schedule.
If your ineffective study habits are:
õ Using your phone to browse the internet when needed
õ Discussing your lectures with a friend
You have to either limit these habits or improve them and make them effective by deactivating your social media accounts so that you will not be tempted to browse them, and only use your phone for academic purposes. And set a certain time when you can study alone if that is more comfortable for you.
