What is the difference between Sonias Portuguese Grammar Book and Sonias Portuguese Course? Do I really need both?
Both materials are completely different and one complements the other. Sonia’s Portuguese Grammar Book is a complete and up-to-date guide to Portuguese grammar and should be used as practical grammar reference book. Sonia’s Portuguese Course is a complete and practical course with over 450 authentic real-life short dialogues and nearly 200 interactive exercises. It gives you the practice you need to master Brazilian Portuguese. Sonia’s Portuguese Grammar Book would complement any practical textbook and is ideal if used in conjunction with Sonia’s Portuguese Course because it complements it.
