Common mistakes to avoid
1. He do ❌
With he, she and it, use does, not do. Say He does his best, never he do his best.
2. She doesn't does it ❌
After doesn't (or don't), the main verb goes back to its base form do. Say She doesn't do it, never she doesn't does it.
3. I make my homework ❌
Choose carefully between do and make. Do = to carry out an activity (do homework, do sport). Make = to create something (make a cake, make a decision). Say I do my homework.

Frequently asked questions
How do you conjugate do in the present?+
In the Present Simple, use do with I, you, we and they (I do my homework) and does with he, she and it (she does her homework). The third person is irregular: do → does, never dos.
Why is it he does and not he dos?+
It is a spelling rule: with he, she and it, do takes -es, not just -s. Go works the same way: goes. Be careful with the sound too: does rhymes with buzz.
What is the difference between I do and I'm doing?+
I do is for habits and routines: I do my homework every evening. I'm doing is for an action happening now: I'm doing my homework right now. The Present Simple says what you always do. The Present Continuous says what you are doing at the moment.
How do you make a question with do in the present?+
When do is the main verb, you still need do or does to make the question: Do you do sport? Does she do her chores? It looks strange, but it is correct. The first do is the auxiliary (the helping verb). The second do is the main verb.
How do you make the negative of do in the present?+
Use don't or doesn't + the base form do: I don't do that. She doesn't do sport. As in questions, do appears twice when it is also the main verb.
