How to Study for Water Treatment License Exams – Part 7 of 10

Spaced Repetition Using Flashcards

Using flashcards to study for your water treatment and wastewater treatment certification and license exams is an excellent way to learn the subject matter that appears regularly on these tests. This is a time proven method that enables the student to focus his or her study time on material that is likely to be tested on a certification exam.

How to use flashcards

There is a “best way” to use flashcards. Our brains learn things best in small chunks over a period of time. It is not sufficient to run through a set of flash cards once and expect to remember what you learned a few days later (unless you have that photographic memory I talked about earlier). It is best to run through a flash card deck several times with at least a day in between sets. After doing this a few times, leave the flashcards alone for three days and come back to them. Then let them sit for a week and go over them again. By using spaced repetition, your memory of the material will move from your short-term memory to your long-term memory and you will be able to recall the information when you need it…during your test!

Most people don’t take the time or make the effort to use flash cards to their maximum. This one little tip can make a huge difference in your score. The wise person will use this strategy to its full potential and be fully prepared to pass their exam.
