After that, <strong>they can easily count their numbers based on the maximum marks achieved on their exams.&nbsp;<\/strong><\/p>\n\n\n\n<p><strong>Explore <a target=\"_blank\" href=\"https:\/\/www.21kschool.com\/np\/blog\/how-to-get-good-marks-in-exam\/\"><strong>how to get good marks in exam<\/strong><\/a>\r\n?<\/strong><\/p>\n\n\n\n<p>Students can easily calculate their percentage by using various percentage calculators. Here are the detailed steps through which you can calculate your CBSE 12th percentage.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Add All Marks<\/h3>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/www.21kschool.com\/sg\/wp-content\/uploads\/sites\/3\/2025\/09\/Add-All-Marks.png\" alt=\"Add All Marks\" class=\"wp-image-13034\" \/><\/figure>\n\n\n\n<p>In the first step, students have to add all the obtained marks for every subject which also includes both theory and practical subjects. For example,<strong> if English subjects are of 100 marks that means 80 marks is for theories and 20 marks is for practical.<\/strong>\u00a0<\/p>\n\n\n\n<p>Let&#8217;s assume, you have five subjects in class 12 and the marks distribution is like that:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td>Subject<\/td><td>Theory Marks<\/td><td>Practical Marks<\/td><td>Total Marks<\/td><\/tr><tr><td>English<\/td><td>72<\/td><td>\u2013<\/td><td>72<\/td><\/tr><tr><td>Mathematics<\/td><td>80<\/td><td>\u2013<\/td><td>80<\/td><\/tr><tr><td>Physics<\/td><td>67<\/td><td>18<\/td><td>85<\/td><\/tr><tr><td>Chemistry<\/td><td>75<\/td><td>20<\/td><td>95<\/td><\/tr><tr><td>Biology<\/td><td>69<\/td><td>19<\/td><td>88<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>So you need to add all the subjects obtained marks.<\/p>\n\n\n\n<p>72 (English) + 80 (Mathematics) + 85 (Physics) + 95 (Chemistry) + 88 (Biology) = 420 marks<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Determine Total Marks<\/h3>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/www.21kschool.com\/sg\/wp-content\/uploads\/sites\/3\/2025\/09\/Determine-Total-Marks.png\" alt=\" Determine Total Marks\" class=\"wp-image-13036\" \/><\/figure>\n\n\n\n<p>Now, <strong>candidates need to determine their total marks by multiplying the number of subjects by 100. <\/strong>For example, if you have five subjects, then you need to multiply it such as 5\u00d7100= 500, so 500 is your total marks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Divide Maximum Possible Marks<\/h3>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/www.21kschool.com\/sg\/wp-content\/uploads\/sites\/3\/2025\/09\/Divide-Maximum-Possible-Marks.png\" alt=\" Divide Maximum Possible Marks\" class=\"wp-image-13037\" \/><\/figure>\n\n\n\n<p>In the next step children have to divide their maximum possible marks by dividing their total marks. <strong>The formula to calculate the possible percentage is Percentage = (Total Marks Obtained \/ Total Maximum Marks) x 100<\/strong><\/p>\n\n\n\n<p><strong>For example:&nbsp;<\/strong><\/p>\n\n\n\n<p>If you have obtained a marks of 450 out of 500 then is how you can apply the formula<\/p>\n\n\n\n<p>Percentage = (450\/ 500) x 100 = 84%<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4.
