Hi there!

I understand you're looking for practice tests for the SAT. Due to the transition to a digital format, Khan Academy no longer offers full-length practice tests for the new SAT.

However, there are still great ways to prepare! Here are two options:

1. Free Practice Tests on the College Board Website: The College Board, the official creator of the SAT, offers free, full-length digital practice tests on their Bluebook app. You can download the app and access the tests there: https://bluebook.collegeboard.org/students/download-bluebook

2. Official SAT Practice Tests in PDF Format: If you prefer paper-based practice, the College Board also offers official practice tests in PDF format for download. You can find them here: https://satsuite.collegeboard.org/practice/practice-tests/paper 

While Khan Academy no longer offers full practice tests, they still have valuable resources for preparing for the digital SAT! They provide free resources specifically designed for the digital format, covering Math and Reading & Writing. 

Hopefully this information helps!
