Description of the bug

During the 3rd problem of contest 323 1792. Maximum Average Pass Ratio, my 2nd submission with Python got TLE. But when I tried this solution after the contest, it got accepted 100% of the time.

Please help re-judge. Thanks in advance!

Code you used for Submit/Run operation

import heapq

class Class:
    def __init__(self, _pass, total):
        self._pass = _pass
        self._total = total
        self._pass_rate = _pass / total
        self._growth_rate = (self._pass + 1) / (self._total + 1) - self._pass_rate

    def __repr__(self):
        return f'<{self._pass}/{self._total}>'

    @property
    def growth_rate(self):
        return self._growth_rate

    @property
    def pass_rate(self):
        return self._pass_rate

    def add_pass(self):
        self._pass += 1
        self._total += 1
        self._pass_rate = self._pass / self._total
        self._growth_rate = (self._pass + 1) / (self._total + 1) - self._pass_rate

    def __lt__(self, other):
        return self.growth_rate > other.growth_rate

class Solution:
    def maxAverageRatio(self, classes: List[List[int]], extraStudents: int) -> float:
        classObjs = [Class(p, t) for p, t in classes]
        heapq.heapify(classObjs)

        while extraStudents > 0:
            minClass = heapq.heappop(classObjs)
            minClass.add_pass()
            heapq.heappush(classObjs, minClass)
            extraStudents -= 1
        return sum(c.pass_rate for c in classObjs) / len(classObjs)

Language used for code

Python3

Expected behavior

The above solution should be AC. However, during the contest it was TLE.

Screenshots

AC:

Tried multiple times after contest, all AC:

Same exact code, got TLE during contest:
