Students often proceed to the next step too fast. The workbooks 'Plus' offer more exercises and new subjects at the same level. This way the student can continue his/her development without losing motivation, which often occurs when the difficulty level is too high. The workbooks 'Plus' contain:
- New subjects
- Broadening of the important subjects
- Subjects from a previous step on a higher level
The answers of the workbooks 'Plus' can be downloaded from our site. See 'workbook answers' in the menu.
