No, students from the Commerce stream are not eligible to pursue BE directly after Class 12. The BE program is a technical and science-based ug degree that requires a strong Physics, Chemistry, and Mathematics (PCM), which are part of the Science stream in 12th and 11th.

Most engineering entrance exams in India—like JEE Main, JEE Advanced, MHT CET, COMEDK, TNEA, etc.—are specifically designed for students who have studied the PCM subjects. Since Commerce students do not study Physics and Chemistry, they are not eligible to apply for these exams and, therefore, cannot enter a BE program.

but i would recommend that, if you're highly interested in engineering despite having a Commerce background, you have to complete 12th with PCM subjects again through National Institute of Open Schooling or a similar board and then appear for entrance exams.

No, you can’t pursue BE after Commerce in 12th. BE requires Physics, Chemistry, and Mathematics (PCM) in 12th. Commerce students are not eligible for engineering degrees.
