first create a structure to hold all the information from one student.

Next you will have to know how to open a file and read it, most likely one line at a time. If you don't know how to open a file and read it then you need to study your textbook about FILE, fopen(), and fgets().

Finally you will need to know how to create a linked list of those structures I mentioned above. Again, your text book will show you how to create a linked list.

After you have started writing your code, you can come back here, post the code you have written, and ask specific questions about what you don't understand.
