We have video explanations for questions that have visual aspects to them - for example: Logic Games, Sufficient & Necessary questions, Quantifier questions.
Main point questions are not visual. All you have to do is break down the reasoning in the argument. What is the author trying to say to you? What is the author trying to prove?
Whenever you have an issue with these just post a question to the message board and we will respond through the message board threads.
Hope that clears things up! Please let us know if you have any other questions.
