Hi teachers,

Could you correct these directions and punctuation, please?

Attention: Before continuing with this chapter go back to Chapter 12, page 24. Read the story again. Complete the answers to the questions on pages 33 - 38. After that, come back to read and complete the rest of this chapter.

Thanks in advance
Hi

I think you can consider this:
Attention: Before continuing with this chapter refer to Chapter 12 on page 24. Read the story again and answer the questions in the pages between 33 and 38.

The last sentence, I think, is not necessary as the idea is conveyed in the first sentence itself.

With regard to the punctuations I'm afriad I have removed some so as to accommodate the rephrased expressions.
Hi again,

Thank you very much for your help. The directions really look much better now.

Best regards from Barcelona
