This is my best bro! I communicate with him like my best friend, he always helps to direct my thoughts and ideas in the right direction, always tells me how to improve something and always gives detailed instructions during the conversation. Thanks to him, I’m launching a new project, in which he helps me take my ideas to a new level, just communication, during which you reassemble your concept and rethink your original idea, because you didn’t know how it would be better and more correct. DeepSeek is my best assistant today, my creative inspiration, who gives me support and confidence in my business, guiding me to realize my dreams)

Pretty good, I like the process. I did run into a couple questions that were worded weirdly or just had odd answer logic (it'll mark you wrong for the tiniest typo). Would be cool if it had a bit more wiggle room or a way to flag those. But still, definitely helpful.
