Do not be worried at all. Inver is slow as molasses at this whole process. They will probably send you a letter sometime in the next few weeks saying your application is either accepted (met all the qualifiers to be put in the pool) or rejected (missing some vital prereq). And also saying that in April they will send out letters. Don't believe that! Count on hearing in Mid-May and try not to worry.
They changed application requirements but I do not believe they changed the number of students accepted. The accepted student rate depends on how many clinical sites Inver has and I have not heard about that changing.
Try not to worry, although I know how it is. It was the worst three months of my life waiting for that stupid letter from Inver!
