How to prepare for bank IT officer examsব্যাংকের আইটি অফিসার পরীক্ষার প্রস্তুতি কীভাবে নেবেন

Know the paper before you study

Officer (IT), Senior Officer (IT) and Assistant Database Administrator posts in the state-owned and specialised banks are filled through one combined exam run by the Bankers' Selection Committee (BSC). Its notices give the same structure each time:

Part	Marks
MCQ, 1 hour	Bangla 10, English 10, Mathematics 10, General knowledge 10, Subject 60
Written, 2 hours	Focus writing in Bangla 10 and English 10, translation both ways 10 + 10, General knowledge 10, Subject 150 (15 questions of 10 marks)

A wrong MCQ answer costs 0.25 marks. Two things follow from this table. First, the subject is 60% of the MCQ and three quarters of the written paper, so it decides who passes. Second, the 40 general MCQ marks are not optional: a candidate who ignores them gives away four tenths of the screening test.

Which subjects to put first

In the 31 bank Officer and Senior Officer papers in our bank, the most asked subjects are networking (123 questions), programming (114) and database (57), followed by general knowledge (48), computer architecture (45), general ICT (40) and mathematics (40).

So a sensible order is:

1. Networking: OSI and TCP/IP layers, IP addressing and subnetting, routing, TCP vs UDP, common protocols and ports, network security basics.
2. Programming: C fundamentals, pointers and arrays, OOP in C++ or Java, tracing code output.
3. Database: SQL queries, keys and normalisation, transactions.
4. Then operating systems, computer architecture, digital logic, software engineering and security.

How to answer the 10-mark written questions

Each of the 15 subject questions is worth 10 marks, and the whole written paper, translation and focus writing included, takes two hours, so every answer has to be short and well organised. A good answer has a shape:

• a one-line definition;
• a short explanation of how it works;
• a diagram, table or comparison (a layered diagram for networking, a table for "difference between" questions);
• a small worked example or code fragment when the question allows it.

Practise writing answers in that shape against the clock. Being able to draw a clean diagram quickly is worth more than a long paragraph.

A four-week plan

• Week 1: networking and programming fundamentals, 20 MCQs a day from each, and two written answers a day.
• Week 2: database, operating systems and computer architecture, plus 10 maths MCQs a day.
• Week 3: software engineering, security and digital logic; start solving one full past paper every two days.
• Week 4: timed mock tests, review every wrong answer, and practise focus writing and translation once a day.

Common mistakes

• Guessing blindly: with 0.25 marks lost per wrong answer, a blind guess on four options gains only about 0.06 marks on average. Guess when you can rule out at least one option.
• Skipping translation and focus writing: they are 40 of the 200 written marks.
• Learning definitions only: many written questions ask for a comparison, a diagram or a short program.
