What would you suggest as the "best" way to approach the lessons in kwizIQ.  The initial test recommended B2.  Is it best to study only the lessons suggested in the dashboard  and trust the system to move me up and also to eventully  fill in gaps from lower levels, or to also take tests for the lower levels and review those lessons, sort of jumping around from level to level, topic to topic.

Thanks!
