Is cheating Ok?

So I have been worrying a lot as of late since my exams are coming up (even if it’s just my mock exams) it’s been stressing me out a lot!! I was never a bad student but never like really really good like I wanted to.
So now I just saw like a specific gadget that has like a camera and stuff and that generally almost undetectable with an earpiece, so James Bond typa stuff.
And I know it sounds weak but as of late I have been seriously taken it into consideration if I should buy it and use it. And I am getting more and more certain that I do want it. But to use it I need somebody that can like tell me the answers and I realize I am to shameless and afraid to ask anybody that I personally know to help me with this (because I have never really cheated or taken into consideration to cheat at such a level before). My real question would be is anyone who can speak like fluent english down to help me or would give me advice to stop and convince me other ways (even though I have to say that I am already quite certain)
Some background info about me: I am an IB (international baccerloria) student its not really a famous graduate pathway but its really international. And my dumbass thought It would be the best to go to the second most competitive school in England for IB and to study with all of these smart ass sorry Asian (that’s not meant in a racist way they are Genuinely really smart because they are really hardworking what I respect but they are also from I think a bit of a different environment, an way more competitive environment straight form schools in Beijing and I am not used to an environment like that) and also the brits that have their GCSEs what the IB is based upon so they have two more years of preperation and English as their mother language (my english is by far not bad but I still lack the ability’s to fully annotate a poem or play with the right Sophisticated vocabulary). I know that even If I don’t cheat that I wouldn’t get the worst mark ever because I am still good in school but its just not the mark that is considered ,with the competitive people surrounding me now, good and that I would like to achieve.
Furthermore I have some trouble also from my family perspective, my siblings are all ten years older than me and two of them have taken the Ib at a time where it was still easier (because they changed the curriculum) and my siblings got outstanding scores and got accepted into Ivy League universities, like Cambridge and Columbia. But I am not as good as my siblings in school but I really don’t want to let my mom down since she is also paying for this school and I am not bad but I am just not outstanding like my siblings!

Wow ok I wrote a lot but my only question would be should I really do it and if yes would there be somebody who is willing to help me?
