It depends. If you’re expecting it to land you a job, no. If you’re trying to add to your arsenal of skills, maybe (arguably you could self teach a lot of it and save your money). If you’re trying to get past HR in some big company who use it’s metric, yeah sure. It also depends on what you want to do - I gather it’s useful for netpens but useless if you want to do appsec, which is a huge chunk of pentest work. What are your end goals?
No goals per se...just kind of interested in the field and would be doing it for personal interest. I've found tons of sites that offer lab environments and downloadable VM's that allow you to practice exploits so maybe that would be a cheaper way to go in the beginning.
