Struggling with LeetCode Easy after doing well on HackerRank Easy — should I move to intermediate SQL?

​ I wanna be straight about this because it’s getting frustrating 😭 I can comfortably solve HackerRank Easy-level SQL questions, but when I try LeetCode Easy, I struggle quite a bit. I’ve seen people say that HackerRank Easy ≠ LeetCode Easy and that LeetCode can require more problem-solving/thinking even at the Easy level. So I’m confused about what I should do next. Should I: - Keep grinding LeetCode Easy until I’m more comfortable? - Or is being able to solve HackerRank Easy well enough to start learning intermediate SQL concepts like subqueries and CTEs, while continuing to practice problem
