Those experience requirements you listed from Bostonair Technical Training's website seem to me to be the minimum requirements for the issue of the A Licence, not the entry requirement for their Basic Module course.
If you get the Modules under your belt, you can then complete any experience requirements, task assessments and OJT that you need to finally get the licence.
Or you can do the Modules while working to get the experience.
