- Prince A8 days agoEasy to follow material. Include more everyday life scenarios in the examples rather than just robots and spaceships.
- Ntuthuko B8 days agoAs someone with some exposure on most of the content, I found it great even with concpets I wasn't too familiar with. The site is worth the money, I'm just unemployed currently, so unfortunately can't commit to it, but for those who can afford to make the investment, it's money well spent I rate.
