Microsoft Virtual Academy is official MS learning resource which provides huge number of free courses. Huuuuge, but not enough. Even with ALL passed courses it is not enough to get platinum certification.
There is hypothetical way to boost you points like free vouchers redeeming or taking a part in some events. But event if you spend 7 day a week on all Microsoft events and grab all vouchers I can’t imaging how other people can get 300,000-700,000 steroid points. It took me about 6 months to get rank #4 in my country (#840 in global) and about 3,000 points. And I still have to wait new courses’ releases to get points for platinum cert. That’s weird.
