Every year, lakhs of aspirants attempt the UPSC Civil Services Exam, but only a few make it through. What separates a successful candidate from the rest isn’t just hard work—it’s smart preparation and avoiding common mistakes that derail success.
We’ve gathered insights from Chennai’s top IAS academies, including Shankar IAS, Officers IAS Academy, Ganesh IAS, and Kanchi Valluvan IAS Academy, to bring you the top 5 mistakes you must avoid in your UPSC journey.
Many students study random topics without even fully reading the official UPSC syllabus.
“The syllabus is your Bible. Stick to it. Frame your notes, questions, and revisions around it,” says a senior faculty at Shankar IAS Academy.
Print and paste the UPSC syllabus near your study desk.
Tick topics as you complete and revise them.
Don’t waste time on irrelevant topics.
Jumping between 10 books per subject leads to confusion, not clarity.
“A focused list of standard books is better than hoarding materials,” says Ganesh IAS Academy faculty.
Stick to 1–2 standard sources per subject. For example:
Polity – Laxmikanth
Economy – Ramesh Singh
History – Spectrum
Geography – NCERT + GC Leong
Many aspirants postpone Mains answer writing till after Prelims. That’s too late.
“Writing practice is what makes or breaks your Mains performance,” says Officers IAS Academy mentor.
Practice 1-2 answers per day
Join a test series
Get your answers evaluated regularly
Improve speed and presentation
UPSC tests retention more than learning. If you study but don’t revise, it’s wasted effort.
“Your brain forgets over 50% in a week unless you revise,” says Kanchi Valluvan IAS Academy trainer.
Weekly & monthly revision cycles
Make short notes & mind maps
Use apps like Anki for flashcard revision
Current Affairs influences both Prelims and Mains heavily.
“Every day’s newspaper is a potential question paper,” remarks a senior faculty at Officers IAS Academy.
Read The Hindu / Indian Express
Make your own monthly current affairs notes
Refer to coaching magazine summaries
Link static topics with current events
Your journey is unique. Comparing your speed or results with others only adds pressure.
Stay focused, be consistent, and trust your process.
