Missing topics?

I just started the one month study plan. I couldn’t really find mixtures, profit & loss, time speed & distance, AP & GP, time & work etc in the GRE Math review book. I had taken up a course earlier and couldn’t attend it. But the teacher had mentioned that these topics would be covered in the Arithmetic section. Am I missing something? Are these topics actually there? I really can’t find it. Maybe I didn’t search for it very well?

Yep , its all covered in Arithmetic and Algebra series
