Well, we don’t know what your 4.9 weighted GPA really means.
But even if we assume 4.0 unweighted in hard courses, you should assume that most admits to super-selective colleges have something extra, whether it is an earned achievement (e.g. some top end achievement) or unearned attribute (e.g. legacy), as well as something compelling in the hard-for-applicants-to-know-how-they-compare essays and recommendations and being what the college itself is looking for (some such things are stated publicly, but others are not – at the very least, check their public statements to ensure that you are not an obvious mismatch).
