Solving the questions for 10 years gives you a rich variety of topics, themes, and question types — factual to analytical.
Why 10 Years Is a Smart Range?
The syllabus of UPSC does not vary much, but the question trend keeps changing. Mid-10 years is quick enough for someone to provide an up-to-date perspective but broad enough to allow you to get a feel for everything. We do not discourage going beyond 10 years, but the cost-benefit ratio may decrease. Current patterns in subjects like Current Affairs and Environment may have changed since the old papers were written, and older papers may not reflect the current patterns.
