I say take the April test and with that in hand you can ask directly if she needs to take it again. If schools are TO and since her grades are strong she will more likely than not still get the nod but be told to apply test optional after the pre-read.
If she decides on one more push after April, I recommend switching tutors. Not that the current one isn’t good but she will have exhausted, if she hasn’t already, what she can learn from them in terms of test taking strategy and all they are doing now is practice accountability. Someone new might offer a different angle that is helpful.
