What is the return value of the field set to? Your code assumes values, but you might want to check it. It could be somewhere in you if/elseif statements.

I would simplify it like this

<?php	
	
	if (have_rows('add_info_exam_grid')) {
		$addclassexamgrid = array();
		$checkboxarray = get_field('add_age_exam_grid');
		foreach ($checkboxarray as $value) {
			switch ($value) {
				case 'Option1':
					$addclassexamgrid[] = 'class1';
					break;
				case 'Option2':
					$addclassexamgrid[] = 'class2';
					break;
				case 'Option3':
					$addclassexamgrid[] = 'class3';
					break;
			} // end switch
			while (have_rows('add_info_exam_grid')) {
				the_row();
				?>
					<div class="grid-item <?php echo implode(' ', $addclassexamgrid); ?> col-md-4 col-sm-6 col-xs-12">
						//Some code here
					</div>
				<?php 
			} // end while have_rows
		} // end foreach
	} // end if have_rows
?>
