You're certainly off to a good start with your first few student reviews! I'm also a tech instructor and am familiar with the subject matter of your course. It seems comprehensive, your audio quality is good, and delivery is good. Some feedback: - While this is a hot topic, you're up against some very tough competition. The top-selling course in this topic has 28.5 hours of content, and a 4.7 review score from over 23,000 ratings. (How he manages to talk about linked lists for 5 hours while still getting great reviews is beyond me, though - and the reviews shown on his landing page don't support a 4.7 score which is weird. But that's another topic.) The #2 top-selling course has 56 hours of content! Even though you have covered the main things you need to know about data structures and algorithms, students will want to see a lot more content before they'll choose your course over these other ones for the same price. (It is possible this world will change when Udemy introduces dynamic pricing, where shorter courses might be offered a lower prices than longer ones, giving courses like yours a better shot.) But, I'd at least recommend exploring the top-selling courses in your topic to see what you can learn from them, and consider expanding your course over time. - There's nothing wrong with your promo video, but making it faster paced and more exciting is a relatively easy way to boost sales. The promo video for the topselling course in this topic is frankly kind of terrible, and the #2 course isn't much better, so it would be one way to distinguish yourself. There are some great threads on this forum on creating promo videos if you search for them. - You'll find that tech students want hands on activities. Many expect every course to basically be a learn-to-code course even when it's about algorithms, and will review you harshly if that's not what they're getting. I noticed you encourage students to "practice with a piece of paper" at the end of your lectures, but they're going to want more. I know your topic isn't language-specific, but showing some examples in some popular language like Python or Java would be a good idea - as well as giving students exercises and challenges they can do on their own. Good luck. I think yours is a good course and I hope it finds success.
