<p>Does anyone here know how to convert the CBT scores to that of PBT and vice versa? I mean is there a definite rule for it? Like how can we compare two individuals if one has given PBT and the other has CBT. Of course in terms of TOEFL only.</p>
<p>This is from the book "The Official Guide to the New TOEFL iBT":
iBt-CBT-PBT
120-300-677
119-297-673
119-293-670
118-290-667
117-287-660/663
116-283-657
114/115-280-650/653
113-277-647
111/112-273-640-643
110-270-637
109-267-630-633
105-260-617-620
103/104-257-613
101/102-253-607/610
100-250-600/603
98/99-247-597
96/97-243-590/593
94/95-240-587
92/93-237-580/583
90/91-233-577</p>
<p>The chart is too long, I can't type all.
79/80-213-550
61-177-500
45/46-133-450/453
32-97-400/403</p>
<p>Thanks. This does the job</p>
