Gamma 40 Hz mixed with Solfeggio 528 Hz – DNA healing frequency for Active learning and problem solving.
This study aid frequency helps to tone brain to Gamma levels which is good for active learning when more brain power and multi processing required which uses many parts of brain simultaneously.
In contrast if you want to memorize something which is also called passive learning low level alpha brainwave will be sufficient – may be 12 to 14 Hz.
