r/IELTS Community Recommendations
Verified: Reddit r/IELTS💬 Cambridge books 11–21 are non-negotiable
The overwhelming consensus on r/IELTS is that authentic Cambridge practice papers are the single most important preparation resource. No other material perfectly replicates the real test.
💬 Mix Cambridge papers with Collins theory books
Many high-scorers report using Cambridge for timed practice and Collins (vocabulary/speaking/reading) to understand why they're getting answers wrong and build their skills systematically.
💬 Don't just read - time yourself strictly
A common mistake reported by candidates is reading practice questions without timing. Always practice under strict time conditions. This is where most people fail, not on knowledge.
💬 For Speaking: Collins > any other book
Collins Speaking for IELTS is consistently rated higher than Barron's or Kaplan for the Speaking module, specifically for Part 2 cue card preparation.
💬 Free resources are underused
Many candidates overlook the free practice tests on IELTS.org and the British Council website before spending money on books. These official free resources should be the first step.
