Code:

BUGS
       Never use this function.  This function modifies its first
       argument.   The  identity  of  the delimiting character is
       lost.  This function cannot be used on constant strings.

Code:

float take_score (char first_names[][MAX_LETTERS], 
				  char middle_names[][MAX_LETTERS], 
				  char last_names[][MAX_LETTERS], 
				  int student_num);

why not use a structure instead of passing the arrays as arguments?

Code:

	char grades[MAX_STUDENTS];
	char first_names    [MAX_STUDENTS][MAX_LETTERS];
	char middle_names   [MAX_STUDENTS][MAX_LETTERS];
	char last_names     [MAX_STUDENTS][MAX_LETTERS];
	float student_grades[MAX_STUDENTS][3];
	float GPAs[MAX_STUDENTS];
	float final_scores[MAX_STUDENTS];

because this is what happens. You've got this completely unweildy grouping of data that really deserves to be put in a structure.

Code:

struct name {
 char first[MAX_LETTERS];
 char middle[MAX_LETTERS];
 char last[MAX_LETTERS];
};
struct student {
 struct name name;
 float grade;
 char letter_grade;
//...etc.
};

// then:

struct student[MAX_STUDENTS];

parsing text can be achieved in many different ways - the most robust implementations typically set up a finite state machine of some sort, simpler ones utilize strtok, strstr, and functions like these:
