If the student failed Apologia Biology, he should retake the course using DIVE Biology. However, if Integrated Chemistry & Physics (similar to Physical Science but with more intro chemistry), was not taken before Biology, he did not learn enough introductory chemistry to understand the biological processes in Biology. If is the case, do one of the following:
If the student is taking Algebra 1, take DIVE Integrated Chemistry & Physics using the accelerated method. Then, take DIVE Biology and list it as Advanced Biology on the transcript.
If the student is taking Algebra 2 or higher, take DIVE Chemistry first, then DIVE Biology. DIVE Biology can be listed on the transcript as Advanced Biology.
