By the time the chapter on arrived, Alex wasn't just copying; he was analyzing. He used the GDZ to verify his work on complex chemical reactions and stoichiometry .
He discovered that "Finished Homework" is only "useful" when it’s the step of the study session, not the first. By treating the GDZ as a verification tool rather than a shortcut, he turned a potential crutch into a roadmap for the exam.

Alex froze. He remembered the answer from the GDZ—he could see the numbers in his head—but he couldn't remember why the coefficients were there. He realized that while the GDZ gave him the , it hadn't given him the process . In 9th-grade chemistry, where topics like Periodic Law , atomic structure , and non-metals build on each other, a missing link in understanding can collapse the whole chain.
