💎 How to Navigate a Chapter on Usmle2Gems.com

(Scroll, Zoom & Fix Loading Issues)

This quick guide will help you get the best viewing experience when using any chapter on Usmle2Gems.com — whether you're on desktop, laptop, tablet, or phone.

__________________________________________________________

⏳ Wait for the Chapter to Load

Once you click on a chapter, give it a few seconds to fully load — especially if you're using mobile data or slower Wi-Fi. A blank screen at first is normal during loading.

__________________________________________________________

🖱 Navigating on Desktop or Laptop

• Avoid clicking the outer gray edge or the “Open in Drive” icon — it’s disabled and won’t respond.

• Left-click once inside the visible chapter area (anywhere within the content preview).

• After that, you can use your keyboard arrow keys (↑ ↓) to scroll through the content easily.

• You may also use your mouse scroll wheel if preferred.

📱 Navigating on Mobile or Tablet

• Use your finger to scroll inside the content, not the surrounding margins.

• The white space around the content is not part of the chapter — you can touch and slide those areas to adjust the visible position for better readability.

⚠️ If a Chapter Doesn’t Load

Try these solutions if you experience blank pages or slow rendering:

• Refresh the page and/or re-login to your account.

• Wait 10–30 seconds to allow the chapter to fully render.

• Try switching to a different browser, such as Chrome, Safari, Firefox, or Edge. For example, if you're currently using Safari, try Chrome, Edge, or Firefox instead.

• Make sure you are using a stable internet connection.

• On mobile, avoid multitasking while loading a chapter.

• If you’re in a region with restricted access, using a VPN may help.

• ​If you see a Google Drive error message and none of the above solutions work, please wait a few hours — it's likely a temporary technical issue with the drive service (rarely needed but usually resolves on its own).
