As you know the syllabus of UPSC is not of some pages. As i don't know your coaching time but let me assume it lets think that your coaching starts from 10am to 5pm then you can do your self study from 7pm to 8pm then make your dinner(if you are living in hostel or in rental room alone) if there is your family member who cooks food for you then study for 8pm to 10pm then have dinner and take a brake from 10:55 then prepare your next subject for studing and then start study from 10pm to 1am then sleep. In morning wake up at 7 am then revised ones what you study earlier then get fresh and start studying till 9 then go for your coaching class.

hope it will helpful for you
