Быстро забыл синтаксический разбор

I don't know the exact translation of "sintaksicheskiy razbor", but if you are having trouble with forgetfulness, there are some strategies you can try. You can try creating a study schedule, breaking down complex information into smaller chunks, using mnemonic devices, and practicing retrieval exercises. Additionally, getting enough sleep, eating a healthy diet, and staying physically active can also improve your memory.
