Syntax: The Complete Crash Course 

Extra practice, a submittable assignment, different shorter-form videos with text lectures in most courses.

I'm not sure if I'd do the Radford book. Its structure is weird and its argumentation style doesn't generalize well. There's also a lot of questionable grammaticality judgments about English sentences. I'd be more likely to do a graduate syntax look based on Adger's Core Syntax or Boeckx's Understanding Minimalist Syntax.

​@@Trevtutorthat would be great too I would like to understand the minimalist syntax

@@Trevtutor Would love to see Adger's Core Syntax or Boeckx's Understanding Minimalist Syntax, thank you!
