: Solutions are broken down by law (e.g., Ohm's law or the photoelectric effect) rather than just showing a final number.
: As textbooks are updated (e.g., the 2022 edition of Myakishev), some older GDZ sites may still host outdated solutions that don't match current curriculum requirements.
: With heavy workloads, these resources help students identify the "starting point" for problems they are stuck on, preventing hours of unproductive frustration. While helpful, over-reliance can be a trap.
