Study plan: 8-week preparation

Here’s a practical 8-week study plan to cover the entire syllabus.

Preparation tips

1. Focus on high-weightage topics

Networking, Computer Architecture, and Programming/Data Structures tend to carry more weight. Prioritise these.

2. Practice previous year questions

Solve previous year question papers to understand the exam pattern and question types.

3. Use standard textbooks

Refer to standard textbooks like:

• Computer Networks by Tanenbaum

• Operating System Concepts by Silberschatz

• Introduction to Algorithms by CLRS

• Database System Concepts by Korth

• Software Engineering by Pressman

4. Take mock tests

Practice full-length mock tests under exam conditions to build speed and accuracy.

5. Revise regularly

Set aside time each week to revise previously covered topics. Spaced repetition is key to retention.

Common mistakes to avoid

• Ignoring less “interesting” topics like theory of computation or compiler design

• Not practising enough numerical problems (subnetting, number systems)

• Cramming at the last minute

• Not solving previous year questions

• Neglecting the general subjects (Nepali, English, GK) in the first paper
