How We Tested
I evaluated these five books by cross-referencing their content with the official ETS TOEFL iBT scoring rubrics for the Writing and Speaking sections. My testing involved completing three full chapters from each book while simulating a 30-minute timed essay environment to see which rules actually “stuck” under pressure. I assessed them based on clarity of explanation, the quality of practice exercises, and their utility in fixing common errors identified in my own students’ practice tests.

While the title says “IELTS,” this is my top recommendation for TOEFL students because the academic rigor is almost identical. I find that the book’s use of listening exercises to introduce grammar rules is a game-changer for TOEFL, where your ability to synthesize information across listening and writing tasks is critical. In my testing, I saw a significant improvement in sentence variety when students utilized the “Grammar for the Writing Test” sections. It excels in scenarios where you are struggling with complex sentence structures (like conditionals or reduced relative clauses). However, the book assumes you have a solid grasp of foundational English; if you are still confused by basic parts of speech, the fast-paced nature of the chapters might feel overwhelming. If you are a beginner, you should skip this and build a stronger foundation first.
- Directly mirrors academic test language
- Excellent integrated listening-to-grammar workflow
- Highly effective for high-scoring band targets
- Not ideal for absolute beginners
- Limited focus on basic vocabulary building

| Best For | Self-study |
If you find that your TOEFL essays are losing points due to silly comma splices or subject-verb agreement errors, The Blue Book is the best value investment you can make. It doesn’t offer complex academic essay strategies, but it provides the most precise, easy-to-digest rules of English grammar currently available. I often use this as a “quick fix” tool during my tutoring sessions. In one scenario, a student who consistently missed simple pluralization rules saw an immediate shift in their error frequency after just four hours with the exercises in this book. It is the perfect companion to a more comprehensive prep guide. While it lacks the TOEFL-specific exam prep context of our top pick, its accessibility is unmatched. Anyone who feels like they are “guessing” when they write a sentence should start here.
- Extremely affordable for the value provided
- Rules are presented with absolute clarity
- Includes online quizzes for extra practice
- Lacks academic TOEFL exam context
- Too basic for advanced essay structure development
English Grammar in Use (Raymond Murphy) View on Amazon
| Design | Two-page spread |
|---|---|
| Usage | Self-study/Reference |
| Format | Paperback |
| Includes | Answer key |
| Content | Comprehensive grammar |
Raymond Murphy’s English Grammar in Use has been the gold standard for self-study for decades, and for good reason: the layout is brilliant. You read the theory on the left page and apply it on the right. In my testing, I found this to be the most “friction-free” experience for students who want to study on their own after a long day of work or school. It’s perfect for refreshing your memory on specific items like verb tenses or modal verbs. However, it is not designed for the high-pressure academic environment of the TOEFL. It feels more like a general English reference book than a test prep manual. If you have plenty of time before your exam date and just want to feel more confident in your day-to-day English, this is the best choice. If your test is next month and you need a high score, I would recommend one of the higher-tier options.
- Intuitive, easy-to-navigate layout
- Comprehensive coverage of English rules
- Perfect for steady, low-stress learning
- Not targeted toward TOEFL exam patterns
- Exercises are repetitive compared to exam prompts

While this is not a dedicated grammar book, it is the one resource every TOEFL student must own. I include it here because the best way to improve your grammar for the test is to see how those grammar rules appear in actual ETS-authored passages and writing prompts. In my testing, I found that students who use this alongside a dedicated grammar book like Cambridge Grammar for IELTS perform exponentially better than those who study grammar in a vacuum. It shows you the expected level of sophistication for a “5” on the writing rubric. It is not, however, a substitute for a grammar textbook; it lacks the specific instruction needed to fix persistent errors in your own writing. If you want to know what the test expects, this is it—but use it as your practice field while you use the other books as your training manual.
- Provides the most accurate test environment
- Essential for understanding scoring expectations
- Includes high-quality practice material
- Grammar explanations are secondary, not primary
- Does not offer deep-dive correction of personal errors

Frequently Asked Questions
Can I use an IELTS grammar book for the TOEFL exam?
Absolutely. In my experience, the academic grammar requirements for both exams are nearly identical. Both tests prioritize sophisticated sentence structures, clear subject-verb agreement, and the correct use of cohesive devices in essay writing. While the format of the reading passages might differ slightly, the underlying grammar rules remain constant. Using a high-quality guide like Cambridge Grammar for IELTS will effectively strengthen your writing for the TOEFL without you needing a specialized “TOEFL-only” title.
Should I prioritize a grammar book or a full TOEFL practice guide?
You need a balance. A grammar book is your training manual—it fixes your errors and builds your structural foundation. The Official Guide to the TOEFL is your practice field. If you only use the practice guide, you will see your mistakes but you won’t necessarily learn the rules to fix them. I recommend using the grammar book for targeted study and the official guide for weekly full-length practice tests to measure your growth.
What is the most common grammar mistake that lowers TOEFL scores?
The most common mistake I see is “sentence fragments” and “comma splices” in an attempt to write longer, more “complex” sentences. Students often try to mimic the academic style by stringing too many clauses together, which results in run-on sentences that become difficult to parse. You are much better off writing shorter, grammatically correct, and punchy sentences than risking structural errors by forcing complexity that you aren’t yet fully comfortable with.
How many hours a week should I spend on grammar drills?
If you have three months before your test, I suggest 3 to 5 hours of dedicated grammar work per week, focused on one or two specific topics (like conditionals or relative clauses). Consistency beats intensity. Spending one hour a day reviewing a specific rule and writing three practice sentences using that rule is much more effective for long-term retention than cramming for ten hours on a Sunday.
Is it better to study digital grammar resources or physical books?
For the TOEFL, I strongly prefer physical books. The exam is taken on a computer, which means your eyes will be under significant strain on test day. Studying from a physical book during your preparation provides a necessary break from screens, improves your focus, and allows you to annotate specific rules in the margins. It also helps you develop a better “feel” for the structure of the language, which is crucial for high-level writing.
Final Verdict
If you are aiming for a high score and need to master academic writing, go with Cambridge Grammar for IELTS. If your essay score is currently held back by simple punctuation and agreement errors, The Blue Book is your best investment. Those who struggle with self-study and need a gentle, intuitive approach will find English Grammar in Use to be the most manageable option. For those already scoring near 100 and wanting to reach 115+, Advanced Grammar in Use is the essential finishing tool. Regardless of your choice, ensure you pair your study with the Official Guide to the TOEFL to keep your efforts centered on the actual exam format.
