How to come to Platinum?How to gain that much xp?
I am still in gold.
Yes, some are. Try to play challenges (the quiz and multiplayer one), you can look at the correct answers after challenges so you would know where did you go wrong and that will help you learn as well.
You have to get 20,000 xp. Play challenges, solve code coach problems. But make sure that you are gaining XPs while learning and by learning. You will see other level requirements here: https://www.sololearn.com/faq/
Thanks for answering. But most of them are for pro.
