Correct:
If I were a president,
1, I would try my best to reunify North and South (Korea),
2, I would reduce some school or kindergarten when students are very tired.
3, Like any president, I would try my best for Korea and people.
Explanations:
1. The modal verb 'would' is used with if in conditional sentences (= sentences that refer to what happens if something else happens)
2. The word 'reunify' means to join together into one country , parts of a country that were divided
3.Be mindful of the proper spelling of words
