After we finish our homework, we must check it carefully and correct our mistakes in time. Mathematics should take a look at whether the calculation is accurate, whether the unit conversion is wrong, and whether the formula of the application problem is correct, and train yourself to correct it immediately after finding the problem; Chinese depends on whether the words are misspelled. After writing the composition, read it yourself to see if the sentences are fluent.
How to improve yourself
Confidence is actually just a state of mind. What you need is to explore for yourself, without too many complicated processes. As long as you have confidence in yourself, then you must be full of strength. Don't care too much about others and don't care too much about what others think of you. We should treat any setbacks with an indifferent normality.
In the new working environment, you can ask the old employees for advice, and they will also provide you with some suggestions or opinions that can help you, so that you can master it slowly and your ability will rise.
