IELTS General Writing Task 1: Informal Letter
IELTS Informal Letter, also known as a personal letter, is an informal type of letter that is usually written to a friend, a family member or someone you know personally.
When it says "write a letter to a friend", make sure you always use informal language. Even if the task asks you to write about work-related topic.
Here is an example how the task may look like:

Be careful when you are writing to your manager/trainer. Many people are friends with their managers/trainers, but please disregard this when writing an IELTS letter. In this case, "manager/trainer" is the same as colleague or co-worker and the letter will, therefore, be a semi-formal type of letter.
Informal tone doesn't mean you can write like you would in a text message to your friend. Therefore, avoid using abbreviations (see ya) and don't use acronyms (OMG). But it's a good idea to use contractions. Using academic language would be inappropriate and will reduce your score.
