I liked the split screen database portal that we worked off of and saw where on the course we were so I can go back to retry the exercises. He was great to learn from - he was engaging and encouraging. I appreciate the training being in my time zone while my trainer is 7 hrs ahead.

Metuatini (aka) Metua - Ministry of Justice
Course - ORACLE SQL Fundamentals
- Learning about SQL and different types of Data bases. - Creating tables with authors and then creating the books and then connecting the information and using those for the sql queries we had - Enjoyed the different scenarios that we could apply certain sql queries. I enjoyed learning about the different 'Joins', calculating average salaries for certain employees as well as many other different sql queries to find out specific information. - The training set up was user friendly and if we had issues on our desktops, Jose was able to remote in and see the issue and resolve.

Luka is an excellent, patient teacher with a sense of humor. His relaxed style made the stressful experience of "be called to the blackboard" more pleasant. Also one student explaining or guiding the other was a very good idea. I will use the motto "KISS methodology" he shared with us in both my SQL exercises , private and professional life since I like to overcomplicate things. Luka also kept the good pace considering how much material was there for him to show and for us to learn.
