I think my proctor will sabotage my test

I will not get into the details of the relationship with my and my test proctor for my upcoming SAT. Let’s just say we’ve a LOT of history. She has tried to get me expelled multiple times and I have tried to get her fired multiple times (I kind of succeeded and got her suspended) . She has said the words “I hate you, I hope you do not succeed” to me. She hates my guts. Imagine the worst relationship you’ve had with a teacher and multiply it by 1,000,000.

Point being: I found out she is my SAT proctor for this upcoming SAT and I am fully confident she will try to change the answers for my SAT to try to change my score. I tried to change my test center but my dad didn’t let me. I worked really hard and brought my score up from 1100 to 1400. I’m a senior, this is the last chance I have (I have an important engagement on October).

Can someone just say something to reassure me that she doesn’t have the ability to mess my test up.

No. If she really does have a vendetta against you and is willing to do anything (including unethical things) against you, she can accuse you of cheating even if you do not cheat.

Ok, but does she have the ability to change my test answers after I hand it in?

Can you take the test elsewhere?

Unless the SAT has changed its security process related to proctors after the Varsity Blues scandal where the corrupt proctor changed test answers to increase scores, I guess it is possible. Those cases occurred in specially proctored tests though where the taker had a special accommodation. There may be better safeguards in a mass center to prevent any shenanigans. Have you tried calling the College Board to express your concerns?
