-----------------------------------) Discipline is the key to crack UPSC, so you need to make a routine/ time table and follow it .

----------------------------------)Read newspaper like the Hindu or Indian Express  and magazines like Yojana, Kurukshetra, Economic and Political Weekly  to keep yourself updated with the current events and issues.

----------------------------------) take short breaks in between your studies, studying continuously can be brain tiring and it becomes difficult to focus and study with concentration, so take breaks to relax and refresh your brain otherwise you won't be able to retain whatever you read.

-----------------------------------)Choose your optional subject wisely , choose the subject you have interest in.

----------------------------------)Make short notes for each subject, these will be your life saviour and will help you in your revisions a lot as syllabus is wide

----------------------------------)Set daily goals like I have to cover these many topics today, weekly goals like I have to  cover these chapters this week and practice their questions too, by the end of this week and similarly set monthly goals to cover the syllabus and meet them without any fail.

----------------------------------)Revise :- there's no point of preparing for the exam if you couldn't recall anything in the UPSC Examination so you should stress on revision as well.

----------------------------------) Your mains examination is in written, so you need to work your speed and also work on improving how to present the knowledge you have on paper, so answer writing practicing should be your priority

----------------------------------)Solve previous year question papers and mock test papers ;- You should solve these , it will give you idea of types of questions asked and their difficulty level and will help you a lot.

----------------------------------)Also work on your communication skills and personality development as it plays an important role in your interview round.
