Having diff VAT for different products

Hello

We currently deliver online training which is only 20% VAT for UK people. Everyone else, oversease, is zero rated.

In the future some of our products (courses) will be classroom. This means EVERYONE will need to pay 20% VAT regardless of where they are from as the course is held in UK.

We will have both online and classroom products at the same time.

How do i set some products to always have 20% VAT on them and others to follow the online rule (UK only 20% and oversease zero rated)

Thanks
