See what students are saying about the comprehensive courses in Rx Bricks:
“It’s very well organized. And daunting topics are created in a very easy way to learn—and quickly!”
“It is the best. So much valuable information. Bricks is a concoction of Harrison, Robbins, Goodman & Gilman, Grey’s and many more books which I don’t have to spend hours reading because Bricks has made it so easy. I’ve started to love studying…which is a big achievement in itself.”
“It’s short, crisp and clear. No nonsense stuff, absolutely high yield. Love it.”
“Rx Bricks are amazing! They are organized so that, even if you don’t remember anything on a certain topic, you will be able to refresh your memory, fill in any gaps, and expand on the knowledge you already have. Having videos and links to the First Aid pages is unmatched. And finally, being able to look at flash cards and take practice questions on the covered topic, solidifies the information in your mind.”
“Rx Bricks remains the easiest to understand collection of high yield concepts for the USMLE exams I’ve come across.”
“Those who are just starting their journey for USMLE Step 1, I do highly recommend this because First Aid is an absolute essential, but oftentimes it gets quite boring and difficult to understand. First Aid tends to give information in a very few lines which sometimes needs more. So at that point, for strong basic understanding [Rx Bricks] is quite a great help. In addition to that, it provides audio clips and different histological and specimen images that often show up in examination.”
