Lexical Resource
Vocabulary range, precision, use of less common items, and paraphrasing ability.

Organize your thoughts with discourse markers (firstly, moreover, in conclusion)
Practice daily for at least 10-15 minutes; consistency beats cramming

What is Voxlio?
Voxlio is a free-to-start, AI-powered IELTS preparation platform built for serious test-takers. Instead of static study material, you practise with authentic exam tasks and receive instant, structured feedback — so every minute you spend studying moves your band score up.
Practice the way the real test works
