Yes, the eBook can be used to prepare for multiple levels of the Swedish language exam, but it's important to note that it covers the material that is typically tested on the CEFR B1 and B2 levels specifically. If you are aiming to take a different level of the Swedish language exam or have a different starting proficiency level, you may need to supplement your study with additional materials or seek out specialized resources to adequately prepare. However, the eBook can still be a useful resource for building a strong foundation in Swedish language skills, regardless of your starting level.
