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.
