Study Tips¶

For Theory Exam¶

Score Maximum

Practice Programs Daily: Write at least 2 programs daily
Solve Output Questions: 80% students make mistakes here
Master SQL: Easiest marks - practice 50 queries
Revise OOP Concepts: Inheritance types, access specifiers
Previous Papers: Solve minimum 5 years

For Practical Exam¶

Common Mistakes

Not writing complete #include statements
Forgetting return 0; in main()
Syntax errors in class definitions
Not closing files after operations
Incorrect SQL syntax

Important Programs to Master¶

Must-Know Programs¶

Class with constructor and destructor
Inheritance (all types)
Operator overloading (++, +, ==)
File operations (read, write, search, update)
Stack implementation
Queue implementation
Array of structures

Must-Know SQL Queries¶

CREATE TABLE with constraints
SELECT with WHERE and ORDER BY
GROUP BY with HAVING
Aggregate functions
UPDATE and DELETE
INNER JOIN

Practical File Preparation¶

Your practical file should contain: - Minimum 20 programs covering all topics - Proper program documentation (aim, algorithm, code, output) - All programs tested and working - Neat handwriting or printouts - Index at the beginning

Prerequisites¶

Strong foundation from Standard 11 C++
Understanding of functions and arrays
