SAT essay

I’m trying to prepare for the SAT, and practiced writing to an essay prompt in the blue book. Im not looking for a perfect 12, but what do you think this would score + any advice/tips?

PROMPT: is deception ever necessary?

The misuse of deception can lead to catastrophic results: accusations are made, trust is lost, and the overall goal becomes compromised. In certain situations, however, deception is necessary. The importance of deception is evident through the imprisoned jews during the holocaust and the need to keep loved ones safe. 
During the holocaust, Jews were beaten, tortured, and starved. The only way for them to survive was through deception. Men would blatantly lie about education, professions, and skills in order to get envied positions, and would secretly receive outside help. Women would make friends with greedy guards in order to receive extra rations, and children would use their petite size to hide from the nazis. Deception was necessary in Jewish camps, for it was the only way to live. 

The importance of deception can also be seen in the protection of loved ones.Through experience, I have learned that not all secrets are best told. Some, if spoken, could lead to disastrous emotional and physical effects. The careful use of deception is the only way to keep the secrets from leaking out to those you care about. For example, in order to preserve the magic of christmas for my youngest brother, I have to use deception. I lie to him about the 8 reindeer that fly through the night, and jolly old saint nick who delivers presents to all the little boys and girls. Although I am deceiving him of the truth, it is for the best.
The uses of deception can vary from evilness to kindness, but whatever the purpose, deception is a crucial tool. It keeps secrets, saves lives, and much more. Therefore, I believe that in certain situations, deception IS necessary.

Your examples about the Holocaust and keeping secrets are quite good. But the essay is a bit short, and unfortunately, essay length has a fairly significant correlation with score.

Also, use correct capitalization (Holocaust, Nazis, Saint Nicholas).

“Evilness” and “kindness” are not uses of deception themselves, so I would reword it a bit differently - perhaps “vary from evil ones to kind ones?” (I’m sure there are better rewordings).

Overall, I think if you elaborate a bit more, you can easily score at least an 8/12, maybe even 10.

thanks! Your advice is really helpful:) @MITer94
