I work in a lyceum. Chemistry teacher appeals to me with a request to conduct testing in my office. I ask a natural question.
- What will be tested?
- In Google?
- o_o
Invites, then, the luminous science of children in the office and says to run Google.
further the following.
- In the search box, write a chemistry test.
- In the list that appears, select the second link.
- And we are testing.
Indeed, great and mighty GUGL.
