The intermediate Grammar Review class is meant for the person who hasn't had an English class in a while and can't find the right one to take because you've forgotten some of the beginning stuff, but you certainly don't need a beginner class. You need a reminder class to fill in the blanks of grammar topics you learned long ago, probably before you needed them as badly as you do now.
We cover the errors we, as teachers, have most frequently seen our students make, and the question we most frequently get asked by adult professionals that are not native English speakers.
