Chapter-wise Highlights & What to Study
Python & Problem Solving
Revise input–process–output flow, dry runs, and tracing. Keep function docstrings short and meaningful. Use list/dict comprehensions sparingly and show the simpler loop method in board answers for clarity.
File Handling & Records
Practice reading a CSV, filtering rows by a condition, and writing results to another file. For binary files, remember rb/wb modes and demonstrate exception handling with try/except.
SQL Queries
Memorize a compact set of patterns: SELECT fields FROM table WHERE condition, grouping, aggregates, and ascending/descending sorts. Write two or three alternate correct queries when possible.
Ethics & Cyber Safety
Define plagiarism, piracy, and open-source licensing in one line each. List two-step verification, strong passwords, and backups as best practices. These are easy scoring areas.
