I'd love to know how people are solving some of these problems without dedicating a week plus to researching.
Even after plenty of research it still isn't even clear if the method you chose to solve is the one code gym is after.
For Java there isn't to much info about the document tree. But if you learn some Javascript basics then working with the document tree is what you do most of the time. Means after that you'll already know the concepts and just have to look up matching methods on the Java side.
I have been with Codegym since 2019 and I would constructively echo that this comment from -- @ibrahim --is the only way to sanely complete 1200 tasks (faster) -- and learn. Beyond Syntax gets increasingly difficult / lengthly (to earn dark matter) and I think reflects on the Advanced level of the super smart curriculum developers. That's is a huge compliment btw ! The Core path is too long and too difficult -- look at the drop out rates and total whom finish to level 40 or 50? I love Codegym ( I have done 2 passes thru ) and think the Levels need to split off at Core into Advanced and Novice thru Intermediate. The Games are great ! Tetris is too long but great ! The Mines Game is just right ! I am also proficient in php - javascript - C++ and C# / Web Dev with long hardcore semiconductor and software work history. Great platform and the Forums and peer comments are worth the Admission ) all the best
