IELTS Grammar App Review: 1,500+ Practice Questions, 18 Topics and 12 Mock Tests
Grammar is one of the quiet deciders of an IELTS score. It counts directly in Writing and Speaking, where repeated structural errors can hold a band back even when the ideas are strong. That is why focused IELTS grammar practice — on the structures the exam actually rewards, with clear feedback on why an answer is right or wrong — tends to pay off more than rereading a general grammar book.
In this review, ChatStick takes a close look at “IELTS Grammar: ตะลุยโจทย์”, an iPhone and iPad app built for IELTS candidates. It combines short lessons on 18 core topics with more than 1,500 practice questions, explanations in Thai, English or both, and tools that pinpoint your weakest areas.
Why grammar matters for your IELTS band
Many test takers already know the rules but still slip on the same points under time pressure: articles, choosing the right tense, or long complex sentences that lose their structure halfway through. Practising with questions that explain the reasoning behind each answer helps turn rules you know into accuracy you can show on test day.
What is IELTS Grammar: ตะลุยโจทย์?
The app focuses only on grammar that is relevant to the IELTS exam. Content is organised as micro-lessons that take about 3 to 7 minutes to read, across three levels — Foundation, IELTS Ready and Band Booster. The 18 main topics include Tenses, Articles, Prepositions, Relative Clauses, Conditionals, Passive Voice and Complex Sentences.
Each lesson explains why the topic matters for IELTS, then walks through rules, structure, examples and tips, and ends with practice. Lessons also flag the mistakes Thai learners commonly make, which is useful for anyone whose first language handles articles and tenses very differently from English.
