I would surely say that among the members i have seen from the time when i joined Brilliant I would say that Finn Hulse, Aayush Mani and Sharky Kesa are really the front runners in brilliant .
Finn Hulse : Finn Hulse really made me surprised when i read his note about length contraction, space time and the Theory of Relativity .
Sharky Kesa : Sharky made me awestruck by his exceptional problem solving skills At the age of 13, he has just proved himself as an exception with solving more than 2000 problems !!!
Aayush Mani : Aayush is really excellent . I just saw his activity part in his profile . He has solved more than 80 problems in just a week with level 5's in every topic. I would surely say that he would crack the JEE advanced easily by securing one of the ranks in top 50
