C :: The Last User Entry In Loop Fprintfed Twice?

Still working on my first homegrown C program design . The function basically allows the user to enter a list of classes and grades and saves the list to a file to be used later in the file. The function compiles and runs through without error except for the fact that it always prints the last user entry to the *profilep file twice. Just as a note, the scanchar function is one I made to scan in one character and an end of line character to throw away the end of line char before I learned about %*c about 30 minutes ago...

Also I haven't much bothered to strengthen the function against crazy user input but I have heard using fgets and sscanf in conjunction can replace scanf and protect against weird user input. How to apply this within the program.

Code:
// creates a new profile and prints it to the profile file.
void newprof(FILE* profilep, const char *allclasses[ABBR_SIZE]){
int c, checker, counter;
int i, a;
char prof[MAX_PROF][ABBR_SIZE];
char grades[MAX_PROF][3];
