CBSE Class 12 Informatics Practices (065) — Chapter-wise Weightage 2026-27
CBSE Class 12 Informatics Practices (065) is a 100-mark subject — 70 marks theory + 30 marks practical. In the theory paper, Data Handling using Pandas & Data Visualization and Database Query using SQL are the highest-scoring units at 25 marks each, followed by Computer Networks (10) and Societal Impacts (10).

Unit-by-unit: where the marks are
Data Handling with Pandas (25): Series & DataFrames, indexing/slicing, adding & deleting rows/columns, descriptive statistics, and plotting with Matplotlib (line, bar, histogram). The single biggest scoring block — master DataFrame operations first.
Database Query using SQL (25): math/text/date functions, aggregate functions with GROUP BY, HAVING, ORDER BY, and joining two tables with equi-joins. Practice writing queries by hand — this unit is pure application.
Computer Networks (10): network types (PAN/LAN/MAN/WAN), topologies, devices, the Internet, URL/WWW, cookies. Mostly theory — quick, guaranteed marks.
Societal Impacts (10): digital footprints, cyber safety, IPR, e-waste. Easy to score if you revise the definitions and examples.
How to use this weightage to plan revision
50 of the 70 theory marks come from just two units — Pandas and SQL. If you are short on time, secure those two first, then bank the 20 easy marks from Networks + Societal Impacts. Keep your practical file and project complete — that is 30 marks you fully control.
