Should I get Career University if I have Power University?
Should I get Career University if I already have Power University?
What's the difference between the two, and is there more in Career University than in the career section of PU?
Short answer:
No, I don't think you should buy Career University if you have Power University.
Longer answer:
Yes, there is something more in CU, like a few paragraphs / strategies more, and a couple of quizzes.
Also, when in the future I will be adding more material, like "interviewing power dynamics", I will most likely be adding them to CU, and not to PU (for the simple fact of keeping PU compact and focused on the most important basics, the 80/20 rule).
However, at the time of this writing, I wouldn't personally advise getting a whole new course that is 90% similar to PU's career section.
Edit: exceptions can apply. For example, if money is not an issue, then it can make sense to get PU, and then switch to CU when one reaches the career section. But otherwise, for most cases, the above applies.
