Thank you guys for the informations
first, I need score of 550 and I scored 533. Second, I do not have problem with reading the passages or answering the questions but most of the time I do not understand what is the passage talking about. Although, when I do the real test in the house I got in rc betwwen 25 and 40/55 but in the real TOEFL I got between 15 and 17. So, please if you can help me by giving me some names of vocabulary books or websites, because, I think my problem is on the vocabularey. Also, can you give me some methods of how to study them.
Thank you again
