CHFI v9 study material

Jay15

Hi all,

I hope you guys are safe and healthy during the lockdown.
I have started looking at the CHFI v9 exam and was wondering if you can advise study material.
I have seen the training course on cybrary from Ken Underhill. Did anyone try it ? Is it good enough to prepare for the exam?
There is also the AIObook for CHFI v8. Is there a lot of overlap between v8 and v9?
Finally, the courseware study guide is a bit too expensive for me $650.00. So I will be looking for materials cheaper than this.

Thanks in advance
Jay

AOI, Sybex,  and  then you can use you tube for examples on how to use the tools discussed in those books.
