When you purchase a BPS Online Review Course package that includes lectures, you gain access to the BPS Online Lecture Center, which provides you with links for each available lecture. You will receive 5 redemption periods for viewing each lecture. To view a lecture, simply click "redeem" next to the desired lecture in the Online Lecture Center and you will be given 24 hours during which you may watch the lecture as many times as you would like. Similar to a digital movie rental, during that 24-hour period of time, you may pause, stop, rewind or forward through the video as much as you would like. After your first 24-hour period expires, you will have four additional redemption periods for that lecture.
