TOEFL reading practice from Graduateshotline

Hello!
I am recently studying toefl since I am going to be having my first exam next month. For me, it is hard to see the questions online with proper level because all the websites provide different levels of questions. One is too easy the other is extremely hard that I wonder if anyone could ever solve. Then, I found a website called graduateshotline. The level of the reading passage is quite hard but I thought toefl would be as hard as the questions there. But when I solve the reading questions I barely get 2 out of 10 correctly and I wonder what the problem is whether it is my fault or the questions there are just too hard and tricky. Is there anyone here who have experience with studying toefl via graduateshotline website? Can anyone pleas tell me whether it is my fault or the questions are too hard? I seem to find answers but then when I correct them I get more than half of them wrong. Please help me!
Thanks in advance :slight_smile:

The passages are the correct length and difficulty level. Many TOEFL preparation books have passages that are too short and too easy. However the questions themselves seem to be a little more difficult that the ones found on official tests. These are closer to questions found standardized tests used for entering Graduate levels of university. The website is targeting students at the Graduate level, and so this difficulty level makes sense.

It isn’t a bad idea to practice with materials that are a little more difficult, but if you are not getting 50% correct, the materials are too hard and you are probably guessing too much.

You should download TOEFL Sampler and the quick preps available for free, there you will find the real difficulty of the TOEFL.
