The student's lawyer said the petition was withdrawn to ensure that her further studies were not affected.
Ameeya had filed the petition before the Kerala High Court claiming that she was given a wrong question paper in the recent Mathematics board exam.
The CBSE, however, had alleged that the student had "fabricated" a story as she was "weak" in the subject.
In its counter-affidavit submitted to the court in response to the student's plea, the CBSE had said that instead of using the 2018 question paper, Ameeya had used her brother's question paper (of 2016) for her Class X board exams, held recently.
The Board had further submitted that the student was weak in Mathematics, and was attempting to mislead the authorities by submitting false complaints to the Board.
The student had moved the court suppressing the material facts and hence, was not entitled for any discretionary relief, the CBSE had said in its counter.
The court had on April 9 admitted the girl's petition, which claimed that she was given a 2016 question paper during the Maths exam and urged that her answer sheet be assessed based on the same.
Principal of Mount Carmel Vidyanikethan Senior Secondary School in Kanjikkuzhy, Kottayam, had complained to the CBSE regarding the mismatch of the mathematics question paper given to the girl student on March 28.
The high court had observed that the pendency of the case would not be a bar for the CBSE to conduct a re-test for the petitioner alone.
In her complaint to CBSE Thiruvananthapuram's regional officer, the principal had stated that their student was given the Summative Assessment (SA)-2 paper of the year 2016 for the mathematics examination.
The principal had appealed to the authorities concerned "to do something" so that the student might not be affected.
