Level 3 is for advanced ESL students. It is not simple English anymore as in Level 1 and Level 2. In this level, we use 5000 most important words in spoken English. We write every word which is from a higher level in bold type. When you practise reading and listening at this level every day, sooner or later you can know 5000 most important words in English and you can be able to understand native speakers.
