Every 2nd PUC student in Karnataka asks the same question: how many marks do I actually need to pass? The answer has two parts. You need 35 percent in each subject, and where a subject has both theory and practical examinations, you need 35 percent in each part separately. A high theory score does not rescue a failed practical, and a strong practical score does not rescue a failed theory paper.
This article gives the exact minimum figures for each paper pattern, so you can work out precisely where you stand in every subject.
The one rule: 35 percent in each subject
Karnataka 2nd PUC follows a simple passing rule. A student must secure at least 35 percent of the marks in each subject. Each subject is marked out of 100 in total, combining theory and practical or internal assessment where applicable. Six subjects therefore give a total of 600 marks, and 35 percent of 600 is 210 marks. But that total is not the whole story, because the rule applies subject by subject. Scoring 90 in one subject and 30 in another does not average out into a pass. The 30-mark subject is a fail, even if your total is well above 210.
The second part of the rule matters just as much. For subjects with practical examinations, such as Physics, Chemistry and Biology, you must pass theory and practical separately. Failing either part means failing the subject, regardless of the total. The same principle applies to subjects with internal assessment: the internal marks are part of the subject total, but they do not replace the theory minimum where the board requires the components to be passed separately.
Theory passing marks: 70, 80 and 100-mark papers
Theory papers are not all the same length: Physics, Chemistry and Biology have 70-mark papers; most humanities and commerce subjects have 80-mark papers; Mathematics and languages have 100-mark papers. The minimum for each is 35 percent.
| Theory paper | Maximum marks | Minimum to pass |
|---|---|---|
| Physics, Chemistry, Biology | 70 | 24 |
| Accountancy, Business Studies, Economics, History, Sociology, Political Science, Geography | 80 | 28 |
| Mathematics, First Language, Second Language | 100 | 35 |
A note on rounding. Thirty-five percent of 70 is 24.5, and most published tables list 24 as the passing mark for a 70-mark paper, while some guides round it up to 25. The safe approach is simple: treat 25 as your target in a 70-mark paper. If you aim for 24 exactly, you are standing on the edge of the rule. Aim a few marks above every minimum in this article, and rounding will never decide your result.
Practical and internal passing marks
Practical and internal marks complete the 100 marks for each subject: a 70-mark theory subject has a 30-mark practical, and an 80-mark theory subject has a 20-mark internal component. The minimum for each is again 35 percent, passed separately from theory.
| Practical / internal component | Maximum marks | Minimum to pass |
|---|---|---|
| Physics, Chemistry, Biology practical | 30 | 11 |
| Accountancy, Business Studies, Economics, History, Sociology, Political Science, Geography internal | 20 | 7 |
| Languages internal | 20 | 7 |
Two practical points follow from this table. First, practical examinations deserve real preparation, not last-minute attendance. Eleven marks out of 30 in Physics practical is not automatic: it requires a working experiment, a correct record and a viva you can answer. Second, do not skip internal assessments, projects and assignments. Internal marks are part of your subject total, and students who have no internal marks to add may find themselves needing the full 35 percent from theory alone. Colleges report this position every year, and it is entirely avoidable by submitting the work on time.
Worked examples: what passing looks like subject by subject
Physics (70 theory + 30 practical). You need at least 24 in theory and at least 11 in practical. A student scoring 40 in theory and 8 in practical has a total of 48 out of 100, but has failed Physics, because the practical component is below 11. A student scoring 24 in theory and 11 in practical has passed, with a total of 35.
Mathematics (100 theory, no practical). You need at least 35 out of 100. There is no second component to rescue or sink you, so the whole subject rests on the theory paper.
Accountancy (80 theory + 20 internal). You need at least 28 in theory and at least 7 in internal assessment. A student scoring 50 in theory but only 5 in internal work has a total of 55, but the subject is still at risk under the component rule, which is why internal work must not be ignored.
First Language. Where the language paper is a straight 100-mark theory paper, the minimum is 35. Where an internal component applies, the same 35 percent component rule governs it, so check your subject’s exact pattern with your college.
Total marks and divisions
Across six subjects, the total is 600 marks. The overall percentage is your total divided by 600, multiplied by 100. Divisions, the class labels colleges and employers use, are commonly described as follows:
| Total percentage | Division |
|---|---|
| 85 percent and above | Distinction |
| 60 to 84 percent | First Class |
| 50 to 59 percent | Second Class |
| 35 to 49 percent | Pass Class |
| Below 35 percent in any subject | Fail in that subject |
In marks, that means 510 and above out of 600 for Distinction, 360 to 509 for First Class, 300 to 359 for Second Class, and 210 to 299 for Pass Class, provided every subject is individually passed. One caution: some college guides label 75 percent and above as Distinction rather than 85 percent, so treat your marks card and college notice as final for your case. What does not vary is the underlying rule: 35 percent in each subject, in each component where components are assessed separately.
What happens if you fail a subject
Failing one subject does not end your academic year. Karnataka’s examination system provides a second attempt window, Exam 2, tentatively scheduled from 3 to 15 May 2027. Students who did not clear a subject in Exam 1, or who were absent, can generally reappear for that subject in Exam 2 under the board’s rules for that year. Confirm eligibility and the application process with your college when the notification is issued.
The practical advice for a student carrying one subject is to revise that subject alone, properly, between March and May, with previous-year papers and practical revision where relevant, rather than re-reading all six subjects.
How to use these numbers in your preparation
Work out your safe target for each subject, not your minimum. If Physics needs 24 in theory and 11 in practical, target 35 and 18. If Mathematics needs 35, target 50. Aiming at the floor leaves no room for a difficult paper or a bad day.
Second, track components separately in your revision record: two columns for every practical subject, theory and practical, each against its own minimum. Third, protect your internal marks early. They are earned over the year through assignments and tests, and losing them makes every theory paper harder than it needs to be.
Frequently asked questions
What are the passing marks for Karnataka 2nd PUC?
You need at least 35 percent in each subject, and for subjects with practical or internal components, 35 percent in each component separately.
How many marks do I need to pass Physics in 2nd PUC?
Physics has a 70-mark theory paper and a 30-mark practical. You need at least 24 in theory and 11 in practical; aim for 25 in theory to be safe against rounding.
How many marks do I need to pass Mathematics in 2nd PUC?
Mathematics is a 100-mark theory paper, so you need at least 35 out of 100.
What is the total passing mark for 2nd PUC?
The total is 600 across six subjects, and 35 percent of 600 is 210, but you must also pass each subject individually.
What happens if I fail one subject in 2nd PUC?
You can generally reappear for that subject in Exam 2, tentatively scheduled from 3 to 15 May 2027. Confirm eligibility with your college when the notification is issued.
