How much does your 2 year old know?

My Jan born ( 2 year 3 months old) took an entrance test for preschool today and here are the questions he had

Identify and name(orally)

1. Animals

2. Fruits

3. Vegetables

4. Colours

5. Parts of the body

6. Shapes

7. Rhymes

My lo did not perform well. He doesn't differentiate colours yet no matter how much I teach him. He talks in one or two words and not clearly and doesn't form sentences yet.

I am worried if i have to be concerned about his not speaking well and not identifying colours

Does your two year old speak fluently and identify the above things well?
