Congratulations¶
Now you have covered 99% of Solidity already. You should be able to read, write and understand all contracts out there - even the most complex ones.
Give it a try yourself! Open up any project, try to read through it. Sometimes it might take bit to understand what a contract does - but the show-stopper isn't Solidity, its what other people do with Solidity.
Also, don't forget to add your own solution to your github. You could also go to the EthDev-Reddit or to stackoverflow and try and answer some basic questions other people might have.
