The Scala creator, Martin Odersky, created a list of "skill levels" of developers with the Scala language.
Here's an overview of how the course relates to these levels proposed by the language creator:

Level A1: Beginning application programmer
Covered: Java-like statements and expressions: standard operators, method calls, conditionals, loops, try/catch
Covered: class, object, def, val, var, import, package
Covered: Infix notation for method calls
Covered: Simple closures
Covered: Collections with map, filter, etc
Covered: for-expressions

Level A2: Intermediate application programmer
Covered: Pattern matching
Covered: Trait composition
Covered: Recursion, in particular tail recursion
Covered: XML literals

Level A3: Expert application programmer
Covered: Folds, i.e. methods such as foldLeft, foldRight
Covered: Streams and other lazy data structures
Actors (*out of scope)
Combinator parsers (*a very specific topic, is now a community-maintained project, not part of the standard Scala library anymore)
Level L1: Junior library designer
Covered: Type parameters
Covered: Traits
Covered: Lazy vals
Covered: Control abstraction, currying
Covered: By-name parameters

Level L2: Senior library designer
Covered: Variance annotations
Existential types (*out of scope)
Covered: Self type annotations
The cake pattern for dependency injection (*there have been complains about the long-run maintainability of this pattern, and other issues)
Covered: Structural types (aka static duck typing)
Defining map/flatmap/withFilter for new kinds of for-expressions (*very specific feature, not needed in most projects)
Covered: Extractors

Level L3: Expert library designer
Early initializers (*very specific feature)
Abstract types (*out of scope)
Covered: Implicit definitions
Higher-kinded types (*out of scope)
