Yes you are right mate this community, is a source of knowledge some older Members/high Ranks members like you created many threads to guide or to discuss bitcoins and related crypto currencies. but not just older members the are few new members here but knowledgeable enough shared their knowledge and makes some thread. Being a new unknowledgeable person if you came here for sure you will feel something good and know more about many discussion.
Your rank on the forum will never decide how much knowledge you have because there are so many hero and legendary members who have no knowledge about Bitcoin and crypto market as a whole and continuing their shill posting.They attained that rank when merit system was introduced in 2018 and were unable to rise afterwards as merits will be given only if you are worthy of it.
This is best discussion forum where ranks are mere formality and your knowledge is that will take you ahead and how much willing you are learn new things.There are so many new members who have contributed well enough over short time and managed to accumulate more merits than their current rank.This is all possible with exchange of knowledge and ability to learn.
This test is only showing you the information about bitcoin and with that also a beginner will know a little about bitcoin, but from another way, the test can not give you total information of bitcoin but it will persuade you to go deep to know things of bitcoin that is foreign to you exactly, but some one have to test it ability after reading any article weather bitcoin or other motivational books, to check if those things read has stick to memory
As i have already said learning is continuous and evolving process and this test is just a formal introduction to the Bitcoin environment with those 50 questions covering some aspects like technical,non technical and economic aspects also.But you need to have more and more knowledge with time that will help you.
