Learned a good amount here. The examples were relevant, though I wished there were a few more practical application tasks. Still, a worthwhile experience.

Hmm, I'm not sure this is for absolute beginners. It assumes a bit of prior knowledge that wasn't explicitly taught. Some examples were confusing.

It's a good course if you have some prior knowledge. For absolute beginners, some concepts might be a bit challenging. The structure is logical, though.

Solid content and presented clearly. I appreciated the real-world applications shown. Could have used a few more practice opportunities.
