The two additions are pretty much identical from the standpoint of material.
The main and only differences are. Here is how Focus differs from Classic:
- Removal of sentence correction question section in its entirety.
- removal of regular Geometry knowledge
- removal of the essay
- questions got mixed slightly differently. Now data sufficiency is mingled with integrated reasoning questions to form a new section called data insights.
As you can see in general, all the materials concepts and what you need to study largely remains the same besides sentence correction and Geometry getting cut out of the new test.
