Best ways to secure better grades in exams found

Surprisingly, common methods, such as rereading and highlighting, get low marks when it comes to effectiveness, researchers said.

"Schools and parents spend a great deal of money on technology and programmes to improve student achievement, even though evidence often isn't available to firmly establish that they work," said John Dunlosky from the Kent State University.

"We wanted to take a comprehensive look at promising strategies now, in order to direct teachers, students and parents to the strategies that are effective, yet underused," Dunlosky said in a statement.

Based on the available evidence, the researchers provide recommendations about the applicability and usefulness of each technique.

While the ten learning techniques vary widely in effectiveness, two strategies - practise testing and distributed practise - made the grade, receiving the highest overall utility rating.

Dunlosky and colleagues report that spreading out your studying over time and quizzing yourself on material before the big test are highly effective learning strategies.

Both techniques have been shown to boost students' performance across many different kinds of tests, and their effectiveness has been repeatedly demonstrated for students of all ages.

In contrast, five of the techniques received a low utility rating from the researchers, according to the study published in the journal of the Association for Psychological Science.

Notably, these techniques are some of the most common learning strategies used by students, including summarisation, highlighting and underlining, and rereading.
