How to practice for the exam without a calculator?

method 2: throw the calculator in the fish tank

method 3: freeze the refrigerator

The above is just a cold joke for myself

The following positive solution:

The calculator has become a kind of spiritual opium for you, and you will feel flustered without it.

The only way is to psychologically affirm one's writing ability and externally match it with some practice.

at the beginning, it will slow down and make mistakes; However, I have to cheer myself up.

Never pick up the calculator again.

once you get a little success, you will have the courage to continue until you win.

Remember: calculators are opium, so get rid of them as soon as possible to avoid getting deeper and deeper. In any case, it can't be used in the end, so it is better to get rid of it as soon as possible.
