Next C++ book or course to do after doing PJA videos?

I've done (70% of) PJA's(Prateek Jain Academy) videos(I'm from India). The course was around 50 hrs long. Now, I'm wondering what course or book to do next. Please suggest some. I don't yet feel comfortable with C++. Should I try unreal engine? Or what should I do? Which book is best for learning C++ at this stage? I just need a quick revision? sadly learncpp.com and cppreference.com didn't work for me because they weren't tailored to my needs which is more of example based, visual explanations.
