A six-question quiz? Pfft, how hard can it be?

Very, according to the vast majority of the population.

The mind-boggling quiz has gone viral this week as people attempt to remember their high school algebra training to tackle it.

The rapid-fire quiz, published by Playbuzz, asks you to complete the "Trickiest Logic Drill" ever but warns that very few can.

According to quiz creator, Cody Cross, only 4 per cent of people who do the quiz are able to score 3/6 or more.

Cross even warns players to be realistic about their expectations of succeeding at the quiz.

He warns not to expect to score higher than 5/6.

Question one offers a series of algebraic sums with multiple answers to choose from, including: 73, 82, 38 or 80.

Question two asks players to pick the word closest in meaning to "effusive" from: "clamorous", "restrained", "gushing" and "windy".

Question three asks which sport is the odd one out: cricket, ice hockey, rugby, softball, soccer or golf.

Question four tests your knowledge of vowels with a simple "Yes" or "No" question.

Possibly one of the most dreaded questions on any school exam, question five tackles the hypothetical calculation, usually involving apples, oranges or steps taken somewhere.

It offers a multiple choice of answers including: 8 feet (2.4m), 15 feet (4.6m), 6 feet (1.8m) or 10 feet (3m).

The final question seems simple enough, but it's sum has stumped the most players.

If you score 3/6 on the quiz, the site will make a pretty blunt estimation of your IQ level (or lack thereof).

"You're probably bored if not engaged, and you constantly require stimulus in your fields of interest," the site suggested.

If you happen to score less than 3/6, "You totally failed this tricky logic drill."

And if, by some miracle, players score the elusive 5/6 or higher, their IQ range is the equivalent of "pilots and scientists".

The reaction to the quiz has been mixed, but most agree it's "way too hard" to complete and threw them for a loop.

"6/6 NAILED IT!" one man wrote.

"But I cheated and had to look up what effusive meant," he added.
