Are IELTS, GMAT, GRE and TOEFL essential to study MBA abroad?

One good book is enough for most students. But many buy 2–3 books, one for official practice and others for extra questions. Avoid buying too many. Focus on quality practice and reviewing mistakes instead of collecting many books.

The Official Guide to the TOEFL Test by ETS is the best. Barron's TOEFL iBT and Cambridge Preparation for the TOEFL are also highly recommended. For Speaking and Writing, use books with model answers and audio. Pick according to your weak sections.

Choose books that match the latest TOEFL pattern. A the latest publications should be priortised. The best ones have full practice tests clear explanations, and answer keys. Always check reviews on Amazon or Reddit before buying. Official ETS books are the safest choice.

It depends on your target score. For 4.5+, free ETS materials + online resources are often enough. For 5+ band scores, paid books give better results because of quality questions and expert tips. Many toppers use both together. Start with free, then add paid if needed.

Yes, for most students it is worth it. Paid books like Official Guide to TOEFL, Barron's, or Cambridge provide more practice tests, detailed explanations, and better strategies. They save time and improve accuracy. Free materials alone may not be enough for 100+ scores.
