i completed the entire Dante lab with a colleague a few weeks before taking the OSCP exam in early September. There are many things in Dante that you will not need to do on the exam (Active Directory attacks, pivoting, etc.). However, the level of difficulty on many of the boxes is similar to what I found on OSCP. Was there anything in Dante that helped me on a specific OSCP exam machine? No. Did going through the entire enumeration process for each of the boxes in Dante help further refine that skill? Absolutely. Being very proficient and persistent in enumeration is the key to passing the OSCP.
