I would be very careful with a program like this. At face value it may seem cheaper but by the time you are paying your university fees, the course will be getting on for integrated prices.
Also so the fact you need to go an instructor rating means that the instrument rating is done when it is convinient for the school. In other words because you are then working for the school you no longer become a customer as such. If the school is busy your IR will be delayed as they need you to instruct.
You would be far better doing modular. You remain the customer at all times and you can save on university fees/FI course. It will be much cheaper- you will also be in employment much quicker meaning you are earning airline wages sooner and not flight instructor wages.
If other students you’ve spoken to at the open day are not happy with their course alarm bells should be ringing.
