Short answer: Start solving papers once you have finished a first read of the core books, then use each paper to decide what to revise rather than to chase a score.
Not too early, not too late
Many aspirants wait until they have finished everything before attempting a paper, while others begin on day one. A balanced approach is to complete one reading of the core books for a subject and then start solving papers on that subject.
Start with previous year questions
Previous year questions show the style of the exam and which topics return. Solve them by subject first, then as complete papers. The routine in our UPSC NCERT reading order guide helps you complete the first read.
Analyse every paper
- Mark each wrong or guessed question
- Find the source line in your standard book
- Add a one-line note to your revision sheet
- Check which options you eliminated correctly
Fit practice with your books
Your standard books remain the source. Practice papers show how the exam tests them. Read which UPSC books to buy new or second hand before adding practice books.
Avoid overbuying
One or two good practice sources are enough. Buying many test books early often leaves them unused.
A weekly rhythm
A workable rhythm is to read in the week and solve a set on the weekend. Alternate between subject sets and full papers so you build both knowledge and stamina. Always give the analysis as much time as the test itself, because the learning happens in the review.
Elimination and guessing
Practice also teaches you when to leave a question and when to eliminate options. Note which kinds of questions you guessed correctly by luck, since those topics still need revision even though they did not cost you marks.
Final thoughts
Do not worry if early scores are low. Their purpose is to show which chapters of your standard books you have not absorbed. As your revision improves, your accuracy usually follows. Keep a simple record of scores and weak topics so that progress is visible to you.
Also decide in advance how many hours you will give to practice each week and protect that time. Without a fixed slot, practice is the first thing to be dropped when the reading load grows. A small, steady schedule is easier to keep for months than an ambitious one that collapses after two weeks.
Where to shop
Compare second hand books and new books, and you can list finished books on the sell UPSC books page.
