Is "I am go to school now" correct?

Why

Reena has correctly noticed that a sentence about something happening right now needs the helper word "am" (or "is"/"are") — that part of her instinct is genuinely on the right track. What the continuous tense actually needs is TWO pieces working together, not just one: the helper word ("am") AND the main verb changed into its "-ing" form ("going"), never the plain base form ("go") on its own. "I am go" leaves the sentence structurally incomplete, the same way a two-part machine missing one part won't run — the helper word signals that an "-ing" form is coming, and without it the sentence doesn't hold together. Test: compare "I am go", which sounds obviously broken to a fluent ear, with "I am going", which sounds complete — that felt difference is your ear recognising the missing second half of the pattern. Her friend is right: the continuous tense needs both the helper word and the "-ing" ending together, not the helper word alone.
