CPP C++ exam — what's the realistic difficulty for someone with 3 years of professional experience?
I've been writing C++ professionally for 3 years, primarily in embedded systems. I'm comfortable with the language fundamentals and I know the memory model reasonably well but I haven't done much with templates beyond basic usage and my knowledge of the standard library is inconsistent.
I'm looking at the C++ Programming Professional Certificate exam and trying to understand whether professional experience translates well or whether the exam tests academic knowledge of the standard in ways that day-to-day coding doesn't cover.
How hard is the template metaprogramming section specifically?
Template metaprogramming is harder than the other sections if you haven't worked with it. Give it 2-3 dedicated weeks. Start with type traits and enable_if, then work toward more complex patterns. It's learnable, just needs focused time.
The C++ Professional Certificate practice questions here cover both the core language and advanced sections. Running through them showed me that my move semantics knowledge was shakier than I thought — perfect forwarding and rvalue references in real code versus on paper are different things.
The standard library coverage is broad — containers, algorithms, iterators, smart pointers, concurrency primitives. Embedded work often involves restricted library usage so if you've been working with a limited subset you have gaps to fill on the library sections.
Professional experience translates well for the core language sections but the exam does test template metaprogramming at a level most embedded developers haven't needed on the job. SFINAE, partial specialization, and variadic templates are all fair game.
