Question

Unknown Questions huh?||
UnAnswerAble Questions !;

Answer 1

Because they ask questions from the entire course instead of asking from start till your current progress.
Complete the course then you can answer them.

Answer 2

That's how we learn.

At the beginning we don't know too much. After answering a bunch of questions wrong, and searching why, you'll be able to answer them.

The questions are separated by languages, so you have at least a bit of knowledge on what you're doing.

Most of the questions are made by community and it seems they're not separated by level of difficulty.

This approach is good to learn. You're going to comprehend.
