Do not make typing speed a major prep priority unless the specific assessment format you received includes meaningful written-response work.

Most preparation should focus on the actual skills and question types tested. Faster typing matters only when it affects completion.

If the assessment includes short text entry, typing cleanly without looking at the keyboard may help, but a few extra words per minute is unlikely to be the main performance driver.

Review the format you were given, then practice under realistic conditions rather than training typing in isolation. If useful, this guide on Bain TestGorilla guide gives more detail.
