I believe the OP should eliminate the table and use an array:
const unsigned int LOW_RANGE_INDEX = 0;
const unsigned int HIGH_RANGE_INDEX = 1;
const unsigned int GRADE_POINT_INDEX = 2;
const unsigned int MAX_INDICES = 3;
const unsigned int MAX_RANGES = 7;

const unsigned int grade_scale[MAX_RANGES][MAX_INDICES] =
{
/*   low  high points * 10 */
/*   ---- ---- ----------- */
    {  0,  59,  0},
    { 60,  64, 10},
    { 65,  69, 15},
    { 70,  74, 20},
    { 75,  79, 25},
    { 80,  84, 30},
    { 85,  89, 35},
    { 90, 100, 40} 
};

/* ... */
/* Look up the grade */
for (unsigned int k = 0; i < MAX_RANGES; ++i)
{
    if ((Grades[i][j] >= grade_scale[k][LOW_RANGE_INDEX])
        && (Grades[i][j] <= grade_scale[k][HIGH_RANGE_INDEX]))
    {
        points += (double)(grade_scale[k][GRADE_POINT_INDEX]) / 10.0;
        break;
    }
}

Or for faster service:
const unsigned int MAX_GRADE_VALUES = 100;
const double grade_values[MAX_GRADE_VALUES] =
{ 0.0, 0.0, /* ... */,
 1.0, 1.0, 1.0, 1.0, 1.0, /* indices 60 ... 64 */
 1.5, 1.5, 1.5, 1.5, 1.5, /* indices 65 ... 69 */
/* ... */
};

/* Look up the grade point */
if (Grades[i][j] <= MAX_GRADE_VALUES)
    points += grade_values[Grades[i][j]];
