This course is helpful, but it requires upgrades to the PowerPoint slides.

Reviewed on Nov 24, 2024

This course was very interesting. It did not get 5 stars as there were far too many typos in the slides and the transcript made little sense at times.

Reviewed on Jul 13, 2025

I found the Introduction to seaweeds to be extremely informative and genuinely enjoyed learning process. Look forward to applying what I learned in my sargassum fertilizer business
