The Sejong Korean series and its new edition.
In the year 2022 the Sejong Korean book series has been completely renewed. The new edition consists of 4 levels, each level is subdivided into A and B, therefore, to complete each level you must complete both parts. Each level includes Student Book, work book, extension Activity Book, Vocabulary and Grammar Book and Teacher's Guide. The Student Book and the extension Activity Book of Levels 1A, 1B, 2A and 2B have 2 different versions: one with the texts in Korean only and one with the texts in Korean and English.
Therefore, this new edition with several books per level is different from Sejong Korean - Revised Edition which consists of 8 volumes.
Do not confuse this new edition with Sejong Korean - Revised Edition. As of September/October 2022, most King Sejong institutes and other academies are still using the aforementioned Sejong Korean - Revised Edition series.
