Are the PCMB magazines available class-wise? Are the magazines useful for class 9 / 10 / 11 students?

Physics for you, Chemistry Today, Biology Today, and Mathematics Today are not available class wise. These cover class 11th and 12th syllabus meant for IIT/PMT preparation. We don’t advise 9th class students to subscribe to these magazines. However, class 10th students can take benefits out of them.
