You forget most of what you learn if your memory muscle is not flexed regularly, especially on complex math equations and the like, so I would say it is useless for those that fall into this category.
But you’ll remember that you solved something “similar” before and know that you can trace back or use some keywords in google/bing/ddg/etc to find a blog or something that goes over it in detail. Helping you solve the issue.
