I totally believe that cheating doesn't do anyone any good.
Though initially, a person might get a good mark, still later on it will show to be more harmful than useful & that is from a life real experience.
Nevertheless, you will always know that you took something in an unrightful way. Really embarassing infront of one's self & very bad for your self esteem. Besides, the consequencies of being caught while doing such an act, and still, I haven't yet started to mention that it's religiousely forbidden.
On the other side, I believe that hard work is always rewarded & that if you REALLY do your best and have faith in yourself & god, you will probably score more than you think (and that too is from my own experience in life)
If you have certain circumstances that makes it impossible for you to do the hard work & get the required score. I still believe that there is always a way around doing the wrong thing i.e, you need the test to immigrate but you can't get the score at IELTS, you will find another way to immigrate without needing the IELTS

..
Believe me, do the right thing & you will see that things will turn out much better than it would have if you did what's wrong..
am sorry if my words might sometimes sound more like preaching, but believe me they aren't just words, they're a resul tof a lige time experience & whenever I worked with it things turn out miraculousely perfect. ..

Just listen to me, have patience and faith & I promise that you won't be disappointed..
best regards..
