my score in nbde part 1 is 87.i have a chance to retake. i m so confused because i heard that difficulty level for retakers is increased. is that true. should i retake or not, or the other way is to take toefl n part2? are there any chances that i get less score then wat i have now. wat should be a wise decision? i dont know where the score graph of 2010 wil go ?
