  I have enrolled for Detailed Design Engineering course. The syllabus is well crafted to cover vast range of topics with assignments for better understanding . The instructor provides good insights to the topics and ensures answering most of the questions raised. Additional topics and software simulations are also given as add-ons. With vast syallabus, it is quite lengthy course, demands time. Pricing is justified to the content and duration of the course.

  I had testing and commissioning background. Am planned to switching the job to power system studies. Then everyone like my colleagues and friends are referred power projects - ETAP course. I had pleasure of participating in power project's training program. It was an exceptional experience. The trainer were highly skilled and knowledgeable. There were able to effectively explain complex in a way that was easy to understand. The course material were comprehensive and organised. I'm grateful for the opportunity to have participated.

  I recently completed power system studies course in Power Projects. The instructors not only covered the material comprehensively but also integrated real-time issues into assignments, enhancing my understanding. Their extensive knowledge and practical experience in the field added a practical dimension to the theoretical concepts. I highly recommend this training program to fellow engineers and fresh graduates, wishing continued success to the power projects team in shaping the skills of future engineers.
