What other people have said

Our thanks to everyone who agreed to share their thoughts. All of the following reviews are from the last 3 calendar years:

"Fantastic, engaging and entertaining trainer who moved us through so many different parts of PowerBI, we really got what we needed out of the course. Every question was answered with ease. We were recommended WiseOwl by another company who had equal success with the training."

Ruth Fowler (MPM Products)

"I really enjoyed the course. I think the content and pace was at the ideal level and the flexibility of the trainer, with structuring the days and allowing space for tangents, was much appreciated."

Dean Zahorodnyj (Atos)

"Our trainer was very friendly and delivered the course in a way that made it fun and enjoyable, but also easy to understand. I would definitely recommend the course to anyone looking to get into SQL."

Katie Horton (The Modern Milkman)

"Really enthusiastic trainer."

Siobhan Thompson (PricewaterhouseCoopers)

"Our trainer was very punctual, arriving early to set up and ensure we had a smoothly run day. The course was very well thought out and delivered perfectly. Working in finance results in lots of Excel spreadsheets. The team only know what they have learnt themselves over the years, and the training allows us to raise everyone's game and give insights into functionality, they wouldn't otherwise have knowledge of."

How our training courses work

Below are some notes on how Wise Owl courses work, to help you decide whether they're for you or not.

What you'll need

If you book on a classroom course, the only thing you need to bring to the course is ... yourself! We even provide a notepad and a suprisingly nice pen for you to take notes with.

For online training you'll need two things:

  1. A good internet connection (otherwise you'll have a frustrating time); and
  2. A second screen (a requirement, not a nice-to-have!)

You can see full details of our online course requirements here.

When you book a place

If you book a place on one of our courses:

  • For classroom courses we will send out a joining email. That's it!
  • For online courses we will get in touch to organise a half-hour pre-course check to iron out any connection problems before the course (rather than during it).

Whatever type of course you book, we will also send you out a reminder a few days before the course is due to take place - not that (we hope) you'll have forgotten!

What you won't need

For classroom training, you won't need a computer - we (obviously) will provide that. However, you're welcome to use your own laptop if you prefer, providing that you have the correct software installed.

For online training you will need a computer, but you won't need to have any software installed.  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.

The start of the course

For online courses you will be able to join up to half an hour before the course begins. This will give you time to:

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

For classroom training it's always nice if people arrive a bit early too, to give people time to meet each other (and drink coffee).

You'll be given a full colour courseware manual, an exercise booklet to go with the course and a USB stick for taking course files away (we'll post all this to you for online courses).

After the course

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

We don't have any formal arrangement for answering questions after the course, but if you get stuck on something and email your trainer they should (and nearly always do!) respond as quickly as their training schedule allows.
