While you listen:

Step 4: Use the given information to help you follow the speaker(s).

Step 5: Write each answer and check that they fit. CARE ABOUT LETTER ‘S’ OR ‘$’

how to do sentence completion tasks

Before you listen:

Step 1: Read the instructions carefully - how many words and/or numbers can you write?

Step 2: Highlight keywords in the sentence and think of synonyms/paraphrases you may hear.

Step 3: Look at the gap and think of the type of word(s) which may complete it.

While you listen:

Step 4: Listen for the keywords/synonyms you have thought of to help you find the answer.

Step 5: Write the answer in the gap. Check spelling and grammar.

how to do classification tasks

Before you listen:

Step 1: Read the complete task carefully - what is the topic?

Step 2: Read the task question. Which words refer to categories?

Step 3: Read the task question. Which words refer to the features or statements?

While you listen:

Step 4: Notice the different speakers and their attitudes and opinions.

Step 5: Write ONE category letter (A, B, etc) next to the features/statements.

how to do notes completion tasks

Before you listen:

Step 1: Read the instructions carefully. How many words and/or numbers can you write?
