Vocabulary Study Online By Level (VSOBL) is an all-in-one tool to prepare English exam vocabulary (US$2/Month). It has built-in vocabularies: 6000 IELTS words, 6000 TOEFL words, 5000 GRE words, and 3000 SAT words. You can load them by level with one click.
The 6000 IELTS Academic Words is an excellent supplement to 4000 IELTS Academic Words. If you finish the latter and still want to enhance your vocabulary skills, this list is an ideal option.
The list actually consists of 2000+ words that are not in the 4000 IELTS Academic Words, low frequency but useful in the IELTS academic test. So it would be best if you studied it after finishing the first 4000 words.
The list has Level 4 and Level 5 of IELTS Academic Vocabulary, following the 3 levels in the 4000 IELTS Academic Words. Each level's words are divided into four groups. We present them as the same as 4000 IELTS Academic Words, including features like online practices, printable materials, and word status management.
