I was shocked to see the results. My name is Swajeet and I'm studying in Class 10. You can submit your subjective answers by taking a photo. I saw that not only were my objectives corrected instantly, but even my subjective answers were graded. They were graded according to the marking scheme, and I could see where exactly I went wrong. I solved a problem without writing the formula, and for that I lost half a mark. It showed me some analysis, and it said that these are your weak topics. "Let's focus on these," and it gave me a set of questions to practise. It's a really good all-in-one solution for us.
