This is more or less false. Most bootcamps don't give 'marks'. Most of them are also not lecture based. Instead, they are likely to assess through assignments and/or projects. They help you progressively build towards a solid base of knowledge while you work on building out a portfolio. I would say the accelerated time span is due to curated resources and the immediate feedback loop. Concepts that normally take a week or longer to grok from searching on the web, can be reduced to a few hours at a bootcamp.

You also seem to think attending a bootcamp automatically precludes a student from being able to provide themselves with continuing education.

There are different motivations for people entering a bootcamp and some are looking for that paycheck. But again, that does not necessarily make them a bad SW engineer. And if those people would like to keep their salary, they will learn soon enough that they will not get very far with stale knowledge.
