Rate USACO Trainings Gateway

I am currently in silver, and aiming for plat next year. How do you guys think about the usaco training gateway? Is it really helpful? Compared to USACO guide or CF problems, is it worth doing? My goal is to make plat by next December, which I would focus on learning gold and plat topics (since I learned all silver topics), and practice problem solving. Let me know whether I should do the gateway problems?

I heard those are a bit outdated. Thanks, and let me know.

Also for those who have done it, at which chapter does it become helpful for gold and beyond?

It’s not good in terms of learning concepts; however, it’s good for improving your logical reasoning skills since solutions aren’t provided :stuck_out_tongue:.
