By Dr. Ingmar Graesslin on 1/14/2024

The course was excellent, featuring clear explanations and instructions that were easy to follow. Fantastic job!

By Pengyi Liao on 7/3/2023

This course is generally good. However, when I ran same code as the Section 3: 10 Query String using the code provided in the Resources. I did not get the same results. I could not build a database (SQLite). I did not know what was wrong. Is there anyone can help me?

By Predrag Milovac on 12/7/2022

The explanations are rough. The course IMO is pre-recorded with voice-over. Sometimes it is hard to understand because he often muffles. The font size is small. No details are explained, for example, instructions on how to install the necessary libraries, etc. The screen is moving too fast; the flow is poor. Also, after comparing it with the other courses, this one was very basic and needed more depth. The only good thing is that it is short (if that can be taken as a compliment).

simple explanation and I love how the way he explain was sooo clear!

By Vishwajit B on 9/17/2022

Very clear explanation. Would have been good if the instructor had covered frond end also and integration with the services he wrote.

By Juan Purata on 6/24/2022

On the moment, the introduction have been clear and useful, I recommend this course completely

By Stas Bard on 6/14/2022

It is not enough to understand a topic - it is crucial to be capable of teaching it to others. This author totally lacks the latter! Waste of time! I do not recommend this course.
