These power lessons are short podcasts (1-7 minutes long) which cover all that you need to know for each topic.

When you have a STUDY BUDDY membership, you will receive weekly POWER LESSONS.

You can also purchase POWER LESSON PACKS and even single custom-made power lessons from our shop.

Choose your power lessons, submit your request to your study buddy, chill for a bit, then before you know it you will have them in your inbox! It should take less than 24 hours for you to receive your power lessons.

Then, once you have them, listen to them on your phone or computer over and over and over and over again, until you have memorised it fully.  You can even write down notes from the podcasts.

These lessons are a powerful way to drill the information into your memory! Enjoy!
