4th edition - Advanced topics for Math guides

[jain.yogesh]

Hello -

I recently purchased the complete set of your 3rd edition study guides and the 11th ed OG a month back or 2 back. I just learned that you have since released 4th editions.
On the website - I noticed that each of the 4th edition guides contain an advanced section - Could you kindly elaborate on whether the content in those sections of each book is also covered in the 3rd edition.

If not - is there any way I can swap the 3rd editions with the 4th?

I hope you guys can help out. THANKS!

The material is already in your 3rd edition guide, but it is not split out into separate chapters. Instead, the material is just labeled "advanced material" within the same chapter as the regular material. We just split it out to make it easier for people - because you should feel really comfortable with the regular material before you try the advanced stuff. :)
