filtered 

When a subject and/or class, usually in higher education scientific fields, is so convoluted and hard to follow, that it is impossible for one to succeed in it. This might be due to the professor, or the subject itself. In this case, the subject acts as a filter, preventing you from moving on to more advanced subjects that built upon it.
This can often extend or apply to specific concepts included or related to a subject or class.
In any of the above cases, it is fair to say that one has been filtered.
-Did you understand anything from the previous lecture?
-No, I'm not even sure the professor understands what he's teaching.
-Huh. I guess we've both been filtered.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
