1 The trick to creating a study schedule is to plan to study the same time every day so you actually have a schedule you can memorize without constantly checking. By creating a routine, youâll build a positive study habit.  Check if there are times or days of the week you can always study during.
Neuroscience research since the late 1990s shows that the brain does not reach full maturity until about age 25, reports the National Center for Biotechnology Information. The brain's frontal lobes â home of executive functions such as planning, working memory and impulse control â are among the last to develop.
Between the ages of 10 and 25, the brain undergoes changes that have important implications for behavior (see Cognitive development below). The brain reaches 90% of its adult size by the time a person is six years of age. Thus, the brain does not grow in size much during adolescence.
