I wrote the sentence
I became the most successful student at the university with this study technique who many professors congratulated.
However, I am pretty unsure about the position of the relative clause "who many professors congratulated".
It is at the end and too far away from the noun "student" it refers to. On the other hand, "became" is a stative verb and we usually use relative clauses at the end in sentences with a stative verb.
In my opinion, the sentence is grammatically correct, what do you think?
