To see if you have quick enough WiFi to run Scratch's terminals, you can freely & securely test your internet speed by following the below instructions:
Google "Free wifi speed test" (or click here). Click the "Run Speed Test" for the first result:
The test takes < 1 min to complete - you'll see your "download" and "upload" speeds (like the images below)...
...then you'll see your overall result (image below)
If you have results of "Very Fast", "Fast" or "Average", you should not have an issue utilizing your internet connection to utilize our terminals. If you see another status, please screenshot your results and email to partners@scratchpay.com for more help & to discuss alternative options.
