How would UCB/UCLA view 3 entire semester's worth of withdrawals?

How badly does having three entire semesters worth of withdrawals look to universities like UCB and UCLA? My GPA is a 3.94, but I literally have three entire semesters of W’s. I came into college with significant AP credits, so as of right now, I have as many W’s as actual completed courses. I explained that it was due to medical reasons in one of the essay questions, but am still wondering how this will affect my chances. Any help would be much appreciated.

Essay isn’t really important and I doubt it has any significance than your UC GPA (still, no BS).
But in your case, your narrative is the perfect reason why they want your essay. You can explain this in your additional note or in one of your essays. Like, you have the perfect reason to withdraw all of your courses.
