I've got a grasp on the basic concepts of data structures, like linked lists, and I can visualize how everything moves around in them. However, when it comes to translating those ideas into actual code—especially for tasks like cloning nodes or finding second prime numbers in a hash table—I struggle to make it work. My exam on hash tables and binary trees is in two weeks, and I need to find a way to pinpoint my weak spots and improve my coding skills in this area.

Sounds like you might have a coding issue rather than a data structures one. Can you write small programs or debug by yourself? If you struggle to convert pseudocode into actual code, it might help to work on your general coding skills alongside learning the structures.
The best way to improve is to write a lot of code! Take the time to implement and use these data structures on your own. The more you practice, the easier it will be to remember the syntax and logic when you're under pressure.
Consider whether you really struggle with understanding the code or if it's just hard for you to remember how to write it. If it’s about memory, try to practice writing code for data structures repeatedly until it sticks. Repetition can definitely help.
