Question

How many repetitions is enough to learn question answer ?​

Answer 1

Research shows the optimum number of repetitions for vocabulary to go into the long-term memory of the brain is 17 repetitions. These 17 repetitions must come in a variety of methods over planned periods of time.

Answer 2

It's well established that repetition is key to memory. But one innovation, called mega-drilling, has proven especially powerful. According to this technique, “you've got to actively recall the memory 30 times,” Cooke says. So when you meet someone new, you might want to repeat her name 30 times.
