I am going to be honest here. First of all, it is way too expensive, you can get much more in courses offered by other sources. Secondly, it barely covers beginner grammar or lower intermediate but entirely skips the essential grammar which might be needed to understand the sentence full.
If you are a full beginner, you might feel overwhelmed with the sentences with no explanation and if you are an intermediate then everything just feels pointless.
Highly won't recommend it to anybody, I wasted my money. Please don't waste yours.
