Yeah, I used to take intersession courses back in my college days where I focused on one course for four weeks. That fit my mode of study way better than taking 4/5 technical courses at the same time. Doing a deep dive on one subject and then moving on was just way better for subject retention in my opinion.

Interleaved study leads to greater retention than blocked study.

What makes you think that it was better?

Condensed studying feels easier, but leads to lower long-term retention. Now, there are methods used to help mitigate that, but those can also be used to increase retention of spread out studying too.
