Hi y'all,<p>Do you know what tools or services exist for me to test my knowledge of certain programming languages? I am confident in my C++ and Python, but am always looking for holes in my understanding, and also for staying sharp.<p>I regularly do interview problems + side projects but this focuses on more on algorithmic and problem solving skills, and not necessary language features.<p>For example, the Triplebyte quizzes for specific languages, but I'm unsure if I can take that without being contacted by recruiters.<p>Thanks!
Pluralsight has self-assessment tests for various languages and technologies - <a href="https://www.pluralsight.com/product/skill-iq" rel="nofollow">https://www.pluralsight.com/product/skill-iq</a><p>I've only done the Python one myself but it did seem to ask questions on some fairly esoteric stuff, from what I vaguely remember.
look for college course syllabus
it is a list of a ratified college lesson plan
if you see anything you dont understand , find somwhere too learn about it.
