What other people have said

Many thanks to those listed below for kindly agreeing to let us use their names. All of the reviews are from the last 3 calendar years (although some may be for classroom courses):

"Had a fantastic 3 days online training. Was a bit apprehensive with it being a fast track course, that I wouldn't be able to take it all in, but the pace was great and learned lots. Our trainer was extremely knowledgeable and made the course fun and interactive. Looking forward to putting into practise all that I have learnt. Would definitely recommend this course for anyone new to Power BI. We looked at the separate 2-day courses but went for the 3-day fast track course and really glad we did."

Donna Wright (Ashton Sixth Form College)

"The trainer was very informative and enthusiastic. He explained things well and went through things in detail. The course was interesting and has helped me understand SSIS better."

Shivani Thakar (BAE Systems)

"Really enjoyed this course. Thought the training was really practical and our trainer was fantastic. Really engaging and made everything very easy to understand. Came away with loads of ideas for my business. Second course I have attended with you. Really impressed by your trainers and how much care and attention you take to delivery and course materials A++++"

How our live online training courses work

We've published a full summary of what it's like to attend a Wise Owl course online - here are the main things you need to know.

What you'll need

You'll need three things for the course:

  1. A computer (obviously) running Windows.
  2. A good internet connection.
  3. A microphone and (ideally) webcam.

In addition you'll find the course very difficult without an additional monitor (so that you can participate in the course on one screen, and use the software you're learning on the other).

What will happen when you book a place

Within a few hours of your booking a place on one of our online courses, we'll be in touch to get you set up correctly.  This usually takes about half an hour, and can be done at any mutually convenient date/time.

A few days before your course begins you'll receive a parcel in the post (free for UK bookings) containing:

  • A full colour courseware manual;
  • An exercise booklet to go with the course; and
  • A USB stick containing the files for the course, should you need a back-up.

Your parcel will even include a Wise Owl Sheaffer biro (they're good; trust us) and pad.

What you won't need

You won't need to install any software at all on your computer.  This is because:

  • you'll use Windows Remote Desktop to connect to our computers, and these will have all of the necessary files and software installed; and
  • we use Teams for our online training, which you can run through most modern browsers.
On and after the course

On the day of the course itself you will be able to join the course up to half an hour before it begins. This will give you time to:

  • familiarise yourself with the set-up;
  • meet your trainer; and
  • get to know the other delegates!

After the course finishes you'll receive an electronic certificate proving your attendance (we will gladly send a paper copy on request also).
