> Study very intensely RIGHT before the test.

I was always told NOT to study right before the test because it hinder retrieval of long term memory.

If the origin of that was a single study, you should learn about then replication crisis in psychology that called into question large swaths of results, after around 2/3rds of studies failed replication.

Both this advice and whatever the OP recommends are both subject to the “replication crisis” critique. At least until you dig in and become confident in the reliability of the research backing the claims. No research is cited in this article. Some of the advice seems unlikely to be research-based (“drink coffee 2 hours before the exam but not right before”).
