Step One of the No-Fail Dosage Calc Method
Memorization stinks. Personally, I try to do as little of it as possible.
But in the case of Dosage Calculations, there is no getting around it: you have to memorize conversion factors.
Even if you master my No-Fail Dosage Calc Method - giving you the confidence to get 100% on all your Dosage Calc exams - you will still get the answers wrong unless you have the most important conversion factors memorized.
The good news is they are not a giant pile of random numbers. They are buddies. And once you understand what that means, Dosage Calcs can get a whole lot less scary.

Tips for memorization
The Toilet Trick
Your brain remembers better when you review things in small chunks frequently over time. That is why the best way to memorize Dosage Calc conversion-factor buddies is to review them in the bathroom 😏
Assuming you drink your recommended amount of daily water, you should have at least five spaced-out review sessions per day to spend with your new buddies. You'll have them memorized in no time!
And let's be honest: you were planning to scroll TikTok or Instagram in the bathroom anyway, weren't you?

Your next step
You don't have to be good at math to be good at Dosage Calculations.
If you can multiply across the top, multiply across the bottom, and divide two numbers (using a calculator, of course), that's all the math you need to master Dosage Calculations.
The tricky part is learning to set up the Dosage Calculation correctly in the first place. And now that you've learned the conversion-factor buddies you need, it's time to learn exactly what to do with them.
