ИДТИ // ПОЙТИ FUTURE Я буду идти в школу (rarely used; I will be going to school) // Я пойду в школу (I will go to school) PRESENT Я иду в школу (I'm going to school) // No option PAST Я шёл в школу (I was going to school) // Я пошёл в школу (I went to school) Идти в школу = to be going to school Пойти в школу = to go to school Я собираюсь пойти в школу = I'm going to go to school In colloquial speech, you can also say (before actually going): "Я иду в школу" ("I'm going to go to school") "Я пошёл в школу" ("I'm going to go to school") A couple of other examples: Он пошел в армию в 19 лет. He entered the army at nineteen. Я, пожалуй, пойду. I better be going.

"Идти" is imperfective, while "пойти" is perfective. "Идти в школу" means "to go to school" / "to be going to school" and focuses on the action of going itself, while "Пойти в школу" focuses more on the destination (the school) and implies that you will reach the destination. "Я иду в школу" = "I am going to school" / "I go to school", "Я пойду в школу" = "I will go to school". "Я шел в школу" = "I went to school", "Я пошел в школу" = "I have started the process of going to the school (and with the intention of reaching the school)".

Я не хочу идти в школу Я хочу идти в школу Я думаю идти в школу или нет Мне предложили пойти в школу Я не могу не пойти, в школе будет экзамен
