Quant asessment quizzes

I tried the quant assessment quizzes (for instance, arithmetic [here] (https://forms.gle/1yNWtpatymwLQFDN7) )

But I’m not sure how many questions should I answer correctly for each section to indicate that my foundation is already good as stated in the video “Being Busy Does Not Equal Being Productive” ?

Something like 70% for Data Analysis 2, 75% for Arithmetic and ~80% for the others would be a benchmark to check whether your foundation is solid.
