The title that now stands out brings in its composition an adjective that by the way reveals itself as the key point of the subject to be discussed – “judicious”. This derives from the abstract noun “criterion”, which leads us to the idea of something pre-established, standardized.
Thus, the purpose of the study in question is simply to emphasize the inappropriate use of some prepositional phrases, in view of the formal character that guides the written modality of the language. A significant example of this occurrence can be effectively verified through a common expression, now materialized by:
At the level of noting the episodes that had occurred, the students suggested a meeting with the principal.
Do not stop now... There's more after the advertising ;)
We see, therefore, a position that, through the grammatical postulates, is in disagreement, given that it is correct to say:
At the level of noting the episodes that had occurred, the students suggested a meeting with the principal.
Starting from such assumptions, in order to further expand our knowledge, let us analyze other cases that also represent this “deviation”. Here they are: 
These are, therefore, trivial expressions whose flaws we are not even aware of, but which, from now on, we will certainly have a broader view of the real circumstances and, with that, we will put into practice everything that we learn.
