Course Reviews
Very informative, all questions answered and was broken down into the correct sized chunks to learn and absorb.

Tarn was fantastic. Very thorough teaching and all in a friendly and engaging manner. I had internet issues that caused me to miss quite a bit of the morning session on day 2 and Tarn offered to stay after the days training had finished to fill me in on what I missed. I really appreciated this and think it spoke volumes about the care and attention Tarn had for our training.
Keean - Apprentice Data Analyst - IT
Tarn was extremely good at explaining concepts, and was always patient in answering questions. A very good instructor.
Neil - tester - Government
Brilliant course Tarn done very very well considering it was all on Zoom. Course content was good and the system was good apart from it kicked me out once for apparently being on too long but it let me back in straight away.
Callum - Data Assistant
Fantastic training that was well paced with good detail. Overcame the barrier of remote teaching. Good online resources that worked well and the use of sql server in utilities focused well to learn the syntax.
