Today is my second day here.
Theoretically speaking, there should be some attachment which is free.
However, according to my observation, majority of the material need money.
To get what you want, (in case it is not free), you need first make some money on your account. then just click the material you want. After confirming the payment, you will see a download link, just click and "save as", you should get the document download to your PC.
I hope this will be helpful.
Thank you.
Good luck.
