DEO most important topics: frequently asked questions
What are the most important topics for DEO 2026?
The highest-value DEO chapters are Grammar (English, about 7.9 MCQs), Vocabulary (English, about 6.3 MCQs), Comprehension (English, about 5.2 MCQs) and Writing Skills (English, about 0.7 MCQs). That ranking comes from the Various Government Departments subject weightage for DEO combined with the chapter distribution measured across the 37 solved papers TestUstad holds for the same chapters. Every one of these chapters has free MCQs on TestUstad.
Is it enough to study only the most important DEO topics?
No, and no honest ranking says otherwise. The top chapters on this page are where your first hours should go because they carry the most marks per hour, but DEO is a competitive exam decided by a few marks, and the chapters at the bottom of this table still appear on the paper every year. Use this order to decide what to do first and what to revise last, not what to skip.
Where do these DEO topic rankings come from?
TestUstad does not hold solved DEO past papers yet, and this page does not pretend otherwise. The ranking is built from the Various Government Departments subject weightage for Data Entry Operator Test, combined, for subjects whose chapters are also examined by papers TestUstad has counted, with the chapter distribution measured across those papers. Each subject page states exactly which of the two applies to it.
How many MCQs is each DEO chapter worth?
Chapter by chapter, that is exactly what the tables on this page show. The single heaviest chapter on the DEO paper is Grammar at about 7.9 MCQs, and the subject pages break down every remaining chapter the same way.
Can I practise the most important DEO topics free?
Yes. Every chapter listed on this page links to free MCQs on TestUstad, with unlimited attempts, no daily limit, no card and no account needed to start. Each question carries a written explanation of why the correct option is correct, so a chapter you are weak in teaches you as you work through it.
