What people say about us

Booking process was very easy. Once initial contact was made everything happened smoothly.

Great course yesterday and can’t give enough amazing feedback for John. I’ve never had a teacher hold attention of a class from start to finish, but yesterday he did this.

Jennifer O'Connor

Alan delivered the training in an easy to understand and pleasant manner which was broken down into manageable chunks with an appropriate number of breaks to give folk time away from their laptops and screens. It is never easy to do 2 days of training on a fairly in-depth subject involving Software even in a classroom environment and remaining focused and engaged so doing it remotely adds another level of complexity, but I have to say that personally this was one of the best Training Events that I have attended for some years. I have gained so much knowledge of MS Project and it will certainly make my job easier going forward.

A large part of what I gained has to be credited to Alan’s manner and delivery and I should be grateful if you could pass on my thanks to him.

Also, the support, together with joining instructions & training literature etc from Nexus Human has been excellent – thank you for that. I intend feeding that back to our People and ICT Teams too

I would like to thank the staff of Nexus Human, who were very helpful, prompt, friendly and professional in helping me attain my Microsoft certification. I would like to thank Abdul in particular for his guidance during the course and commend him on his knowledge of software development.

This is the 3rd course I have done with Arun. He is very helpful and always supportive if I have other questions outside the lecture parameters. I have already recommended him and Nexus Human to work colleges and would do so again after this course.

Nexus Human Classroom Student

The instructor was excellent. Was willing to field any questions we had and deal with our specific queries.

Excel student

The class just finished and I just wanted to mention to you that it was absolutely amazing. The quality of the training had very high standards, the trainer explained amazingly well and we actually practiced (did) all the steps. It was not learning by watching a presentation but by actually doing. The training has been delivered from Atlanta (US) and I cannot wait to go tomorrow in the office and recommend it. The connection and the lab environment were running perfectly.
Once again thank you very much and looking forward for the next trainings scheduled. Enrolling via Nexus Human was the perfect choice.

Cristina, Nexus Human IT Course Attendee

Firstly I would like to say thanks, I found the course I sat yesterday extremely beneficial and the instructor was fantastic, she was enthusiastic and engaging and I would highly recommend the course to friends and colleagues. The post class services are also excellent!

Adobe Student

Sharon was lovely and has a fantastic knowledge. Honestly I didn't think I needed part 1 but I am SO glad I came. Thank you. Will be back in for part 2.

Nexus Human Student

Excellent interaction and answered all of my questions. Looking forward to being able to apply some of the tips and features learned today which hopefully should have real impact on some of the more time consuming tasks currently encountered.
