Unfortunately, no. In our experience after teaching hundreds of high school students, every student will learn something new in the first level. For some there may be some review, but we encourage that. We build the students up from the ground level to ensure that their Arabic knowledge is sound. If a student skips a level, they are at risk of having large gaps in their knowledge. We have had native speakers, huffadh, and others all start from the beginning, but everyone has found it to be the correct decision.
