Checklist, do and avoid

Do

• Learn in small sets, 3 items per day, 15 per week, review on day 6.
• Pair each headword with a collocation and an audio line you can shadow.
• Track progress with a simple table, term, gloss, collocation, example line.
• Use British spelling where relevant, programme for government plan, program for software.

Avoid

• Memorising rare buzzwords without context.
• Translating whole sentences into Bangla, keep gloss short, 1 to 3 words.
• Overusing cutting edge terms in basic prompts. Match register to the task.
• Mixing similar ideas, AI and automation are not the same.

Deck items by theme, with Bangla gloss and audio

Digital infrastructure

  Collocations: intuitive interface, interface redesign
  Audio line: An intuitive interface reduces training time.

  Audio line: Users must give informed consent to share data.
• encryption [এনক্রিপশন]
  Collocations: end to end encryption, encrypt files
  Audio line: Chats use end to end encryption by default.

Emerging tech and impact

• automation [স্বয়ংক্রিয়করণ]
  Collocations: workflow automation, automate tasks
  Audio line: Workflow automation saved hours in the office.
• artificial intelligence [কৃত্রিম বুদ্ধিমত্তা]
  Collocations: AI tool, AI policy
  Audio line: The AI tool drafts summaries for editors.
• bias [পক্ষপাত]
  Collocations: algorithmic bias, reduce bias
  Audio line: Teams test for algorithmic bias in hiring.

Study checklist with quick wins

Daily loop, 7 minutes

1. Read the headword and gloss.
2. Say the collocation aloud.
3. Shadow the audio line twice, record once on your phone.
4. Write one sentence of your own.

Measured targets

• 15 items per week.
• 1 recorded 60 second monologue on Sunday using at least 6 items.
• In writing, upgrade 4 vague phrases to precise collocations, for example improve the internet to expand broadband access.

Examples

Example 1, Writing Task 2 upgrade
Weak: The internet is sometimes slow.
Better: Peak time bandwidth caps and latency spikes slow video classes in Dhaka.

Example 2, Speaking Part 3 line
Strong: Open source software lowers entry costs, while a clear user interface reduces training time for small firms.

Mini case, Sylhet student

Meher prepares for a tech topic interview. She picks 12 items, runs the daily loop, and records two monologues. Old answer: I used an app that helps me study. New answer: I used an AI tool with an intuitive interface to plan sessions. It worked well after a security patch fixed a bug. In one week she moves from general words to specific lexis with natural collocations.

Mistakes to avoid

• Writing algorithm when you mean policy. An algorithm is a step by step method, policy is a rule set.
• Saying data is or data are without thinking. In formal reports, data are, in everyday speech, data is. Match the register.
• Using AI to mean any automation. Many tools are automated without AI.

Edge cases

• British vs American usage, programme for a plan or event, program for software.
• Pronunciation traps, say latency with a clear t sound, say anonymise with stress on a.
• If your centre bans phones in study spaces, write audio lines on cards and shadow from memory.

Mini glossary

• Algorithm: method a system follows to solve a task.
• Bandwidth: maximum data transfer rate of a network.
• Latency: time delay between request and response.
• Encryption: method to protect data by encoding it.
• Open source: software with source code shared for use and change.

Actionable closing
Choose 9 items from this deck. Make three cards per day with gloss, one collocation, and one audio line to shadow. Run the 7 minute loop and record a 60 second summary on Sunday. In your next essay or answer, replace two vague phrases with precise pairs, for example expand broadband access or reduce algorithmic bias.
