I bought the "Official TOEFL iBT Tests with Audio Volume 1" (2014) today. It contains 5 real past tests from ETS. However, it does not provide any scoring guidelines. It provides information about the 4 sections and gives an overview regarding what one must do in each of the 4 sections. So I have got an idea about what the test is all about but I can't score myself or judge my performance using this book.

I also borrowed "Barron's TOEFL iBT Guide" from a friend which happens to be a publication of 2010. Even that book contains individual sections for practice and does not provide any way by which I can get an idea of what my score would be when I give the actual test this Saturday.

Is there any free test available by ETS online which would help me get an idea about where I stand at the moment? Or any other practice test which would score my performance?

Thanks in advance!
