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.
Not sure this was the best way to learn this. The examples felt a bit dated, and the overall structure was confusing. I needed external resources to make sense of it.
Hmm, not sure if this is for absolute beginners. Some parts were tough to follow without prior knowledge.
Found it useful for a refresher. Not sure it would be the best starting point for a complete beginner, tbh.
Disappointing. The content was poorly organized and the examples were confusing. Didn't achieve what I set out to learn.
Found it helpful, but it might be challenging if you're completely new to the subject. Some explanations were a little vague.
