Here are the essential tips you need to know in order to study with intense focus:
Protecting your blocks of focus
Get rid of shallow, low-intensity work and stuff like checking social media on your smartphone, while you focus on your study work. Keep yourself distraction-free at least for the few hours you are studying.
A weekly plan
While focusing on one topic in a day, it helps to have a weekly plan to organize yourself and map your study hours.
Doing one thing at a time
Commit to what you want to study on a particular day, or for a few hours. Limit the number of tasks/distractions/subjects so that you keep your intense focus and actually complete the tasks you started.
Find and develop a routine
A routine will ensure your time is well utilized and you have less unexpected distractions.
Get yourself comfortable in your study table or a cafe where you will not be disturbed, and can tune-out the music or noise to focus on your study work.
Make focus a lifestyle choice
Make focus a regular part of your lifestyle, by practicing it progressively on a daily basis.
This means making a commitment to stop using your smartphone for a few hours daily, or not checking it first thing in the morning.
Take time out to rest
Sleeping 8 hours a day and taking a time-out to rest is crucial.
Give yourself time to recuperate, in order to perform better at any task, and to recall better what you have studied.
