I will be your tutor, if anyone needs one.
I have never taken Series 7, or 8 or 9 or 10, but I know the basic ways of dealing with an exam that is based on a single book. There is no easier exam than that.
When I took an exam, I usually answered 99% of the questions correctly. For the 1% I was considered incorrect, it was often a matter of disagreement. If I made the key, it would be my answer being correct.
By the way, I don't understand why traders need to pass this exam. If it is a broker, he may need it to explain something to customers. But the way ES moves is totally independent of how much you know about option. I know nothing about option, and I don't want to know option, and I will never even want to touch option. There are enough moving things in the market that produces money for you.
