Hey, I'm Harry

When my journey began, I was an engineer at Transport for London wrestling with off-the-shelf simulation software trying to figure out how to build probabilistic models of the London Underground.

Eventually, enough was enough when I was quoted outrageous license fees for simulation software - this didn't feel like value to money to me.

I was inspired to dive deep into Python and simulation. That’s when I discovered the power of Python-based simulation with SimPy - a flexible, scalable, and transparent way to solve even the most complex challenges without relying on expensive, rigid software.

I started building my own custom tools and simulations and applying them to real-world projects. I combined everything I learned about systems engineering, coding, and stakeholder management to drive results.

Simulation is the beating heart of everything I do now. It's how I 10x'd my annual earnings over my 14 year career and achieved financial freedom. It's how I enjoy a fully flexible, remote lifestyle. And it's why people seek me out from all over the world for help with their modelling and simulation projects.

Based remotely across Bermuda and the UK, I enjoy rum-fuelled island life with my beautiful wife and son, while helping others to create their own success stories.

Need help?

Don't worry, I've got you. Here are some answers for your questions.

What level of Python skills do I need for this course? Do I need to use a particular interactive development environment (IDE)?

You should have a basic familiarity with Python. If you are not quite there yet then I recommend taking my 10-day Python bootcamp course on Udemy. You don't need to have software engineer level knowledge. The lessons focus primarily on single file scripts.

I have a lesson at the start on using Jupyter notebooks, but you are free to use any interactive development environment (IDE) that you please. I recommend either Thonny, Spyder or Jupyter Notebooks (the latter two can both be easily installed by downloading the Anaconda Distribution.

Do I need to complete all the material sequentially and is there a time limit or is the material self-paced?

Everyone learns in their own way and at their own pace. To maximise flexibility, the material within the School of Simulation is entirely self-paced. You get lifetime access and unlimited access to future updates as they arrive. The structure of the material is designed to progress chronologically from beginner to advanced topics, however you are free to dip in and out as you please. You can get through all the content as fast as possible if you have the time, or you can dip in and out as needed months or even years from now.

One thing off the shelf-simulation software provides is visualisation which is useful for communicating the ideas and dynamics in a simulation. How do you approach the visualisation aspect?

Most of the impactful visualisation is done during the conceptual model design phase. Think mapping out process flows in a visual way. Nowadays this can be done so nicely with digital whiteboards. You can map the system out on a whiteboard and use this model to engage stakeholders to (1) get them onboard, (2) get assumptions, (3) get their feedback on the model and (4) show them how it works. Then when it comes to running the simulation your stakeholders are already engaged and are generally happy just to see the data. I call these "warm" stakeholders as they have been warmed up.

If you are engaging with stakeholders that are "cold" (i.e. they haven't seen your work yet). You can show them the conceptual model design, this is usually effective. But sometimes yes you need an animation instead, especially if this is for very cold stakeholders like if you are presenting your results for the first time to a room full of skeptical decision makers. For animation you can use Pygame or Tkinter which are pretty easy to build animations with. I've tested this with success with stakeholders in presentations at the London Underground and at Anglo American.

All of this is covered in-depth within the School of Simulation.

What if I’m not confident in my simulation abilities?

Don’t worry - this course is built for you, even if you’re just starting out! I’ll guide you every step of the way, from fundamentals to advanced simulations. With clear explanations, practical examples, and plenty of support, you’ll come to realise just how capable you really are.

How long do I have access to the platform?

You get lifetime access to the platform. That means you can revisit the material anytime you like - whether you’re brushing up on a module, diving deeper into advanced topics, or tackling a new simulation project months or even years from now. The platform is designed to grow with you, so you can progress at your own pace, and as your career evolves, you’ll always have a trusted resource to come back to.

Plus, you’ll get access to any future updates, so you’re always learning with the most up-to-date methods, tools, and best practices. No deadlines, no pressure - just learning on your terms, for life.

I'm in this for the very long term, but if for some unexpected reason I am forced to close the platform I want to reassure you and promise two things: (1) I will give you plenty of notice and (2) I will make all the video lessons downloadable so you can keep them for life. The code examples and templates are already downloadable for you keep and use to your heart's content.

The platform is designed to grow with you, so you can progress at your own pace. You’ll get access to all future updates, so you’re always learning with the most up-to-date methods, tools, and best practices.

Do I have full access to all the material in the platform from day 1?

Yes!

Everyone learns at different rates and people engage with the platform in different ways so I don't force you to engage with the platform in a particular way. Some people prefer to treat it like a reference book - dipping in and out of different sections as required or when they need to refer for something for a project. Others prefer to work chronoligically through the material - I have structured the material to flow logically from start to finish making it well suited to chronological progression.

If you're not ready to commit now, since you have lifetime access you can take advantage of this price now and revisit the material when you are ready. As the platform ecosystem grows it is likely that I will increase the pricing in the future.

You can download and keep the code examples and templates at any time.

What if I don't have access to specialised software or tools? Do you give me a complete education in SimPy?

You don’t need any! This course uses SimPy, a free, open-source Python library. All you need is a computer, Python installed (I’ll show you how), and the willingness to dive in - no pricey software or subscriptions required.

And yes! We will cover every aspect of SimPy, with plenty of unique industry examples - and all the code is downloadable. Say goodbye to toy examples you might have seen like the "machine shop" and "car wash". Say hello to proper heavy industry examples like "green hydrogen production", "producing steel in a plant", "modelling a GPU server", "supply chain distribution sytems" and "precious metal mining" to name but a few.

This isn't the entirety of the content though. I want to stress that we will focus heavily on real-world application with proper industry examples and case studies. We will also cover conceptual model designs (going from visual modelling to simulation code), other Python libraries and how to integrate them, stakeholder management and leading simulation projects. So you will have a complete toolkit for real-world industry application.

What is the sound quality like and are you understandable to a native English speaker? What about accessibility for hard of hearing?

I use a proper microphone for all recordings and de-noise in post-processing, so sound quality is good. I am British and grew up around London in the UK - so I speak with a fairly traditional English accent which should be widely understandable by English speakers.

All of the video lessons come with optional English subtitles for viewing without sound or for people with hearing disability. I currently only offer English subtitles.

Can I get a refund if the School of Simulation is not for me?

Enrolling is 100% risk free - you get my ironclad 30 day moneyback guarantee. If you are not happy for any reason then I will provide you with a refund, no questions asked. It's easy within the platform to do this with the "request refund" button. Any hiccups you can email me harry@teachem.digital and I will help you out.

How long will it take me to get through all the content?

If you are committing about 2-3 hours a week to this and completing the assignments and practicing, you should be able to achieve your transformation in 2-3 months. I will be adding more content as time goes on, so this baseline amount of time will increase to cover all of the content. The great thing is you will have access to these future updates, so you can continue to bolt-on additional self-improvements as I release them to the platform.

Still on the fence? Listen, I get it.

Investing in yourself can feel risky, especially when you’ve tried learning before and didn’t get the results you wanted.

But here’s the thing…

This isn’t just another set of tutorials or disconnected lessons. It’s a proven, step-by-step system designed to take you from uncertainty to mastery – so you can finally feel confident building powerful simulations and unlocking opportunities you’ve been dreaming of.

I can’t promise you instant results or overnight success – because we both know that’s not how real growth works.

But I can promise you this:

I created this course with you in mind - the ambitious professional who’s tired of feeling stuck and is ready to stand out. I’ve poured 14+ years of experience into this program to ensure it’s practical, clear, and actionable. Your success matters to me, and I’ll be there to guide you every step of the way.

And if all that fails, you’re covered by my 100% money-back guarantee. If you’re not completely satisfied within 30 days, I’ll refund every penny - no questions asked.

So what’ve you really got to lose?

Let’s make this happen,
