I recently completed one of Advisera ISO's courses and was delighted at the high quality experience. The instructors clearly knew their material and provided invaluable tips from years in the field. The video presentations and the quizzes were intelligent, definitely not just tick the boxes. The workshop and the instructor were engaging. And the pricing model of give away the course material and pay for the workshop and final exam aligns with modern online courses. I chose Advisera for the flexibility in taking the course and their price was half of their competitors, including a Big Four global consultancy. Top marks!
