I’ve written explanations for LSAT preptests 29-38.  They’re available for sale on LSAT Blog.  For each question I’ve:

• Identified the Question Type
• Identified the Conclusion and the Reasoning (If it’s an argument)
• Written an analysis of the question’s logic
• Written explanations for why the right answer is correct and why all of the wrong answers are wrong.

I know it’s hard to decide if something if useful without seeing it first.  So I’ve posted a sample.  The explanations for the first half of preptest 29 are available for free.

If you think the entire set will be useful, buy them on LSAT Blog.
