Why did my First Aid / Flash Card / Video stats change when I switched from 2019 to 2020 First Aid?

When switching First Aid years, you may notice differences in your overall confidence ratings & stats. This occurs because not all First Aid years contain the same content. Some First Aid topics exist only in a specific First Aid year. Cards and videos that do not change between years are mapped directly from 2019 to 2020. New cards and videos are displayed as new (unused) content in 2020. Some cards and videos may not exist in both years, those would not be included in the 2019 Stats.

Here is how the confidence level is calculated and displayed in USMLE-Rx.

30% of cards must be assigned a confidence level before a category is color-coded.

Default (no confidence ratings, less than 30% of cards rated) = Blue

0-49% Correct = Red

50-74% = Yellow

75-100% = Green

New and removed cards between First Aid years will affect the topic’s confidence rating (color).
