CBSE 10th Maths 2025: Exam Analysis, Unofficial Answer Keys (Sets 1-3)

CBSE Class 10 Maths Exam—2025: The Aftermath

So, the CBSE Class 10 Maths exam on March 10th, 2025, is officially in the history books. Whew! I bet you’re all wondering how it went, right? Everyone's buzzing about it, trying to figure out how they did. I've got some insights into the exam, including unofficial answers for Sets 1, 2, and 3 (Standard Maths). This should help you get a general idea of your score and where you might want to focus your energy if you need to.

What Was the Exam Like?

It was an offline exam, which, let’s be honest, is pretty standard for CBSE. The Standard paper had 38 questions adding up to 80 marks, with a 3-hour time limit. Everything was compulsory, although some questions gave you a choice between a few different ways to solve them. From what I’ve heard, most students found it to be a reasonably tough but fair test – a good mix of straightforward questions and some real brain-ticklers that really made you think. Basically, if you'd studied, you probably felt okay, but if you hadn't, then, yeah….

The Buzz Around the Exam

Talking to students and teachers, the general feeling is that the paper was pretty well-balanced and stuck pretty closely to the NCERT syllabus. That said, there are always a few tricky parts, right? This time, a lot of people mentioned some of the multiple-choice questions and the application-based problems as being particularly challenging. It also sounds like the difficulty level varied a bit between the different sets – some folks found Set 1 tougher than Set 2, with a few questions on coordinate geometry and trigonometry getting singled out as real head-scratchers.
