levels and access to membership levels

i was just wanting to clarify that we're implementing the levels in the most affective way.

we have 3 courses that have a level each and an all-access level which covers the 3 courses in a bulk buy.

for displaying content in these relative situations would it be best to use both [level-access] and [not-level-access] to flip between both in the same view?

you have access to the site/admin through wpmudev and referencing http://www.creativestudiosderby.co.uk/your-subscriptions/ would help you understand the question.
