You can write the above entry as follows:

If I could choose a superpower, I would want the ability to predict the future.

Using my ability, I would see the questions for all exams beforehand so that I could get a perfect score in all of them.

Then I would use it to sell my stocks when the market is at its peak, to get rich.

I would also use my ability to know the winning number of a lottery.
