Hello,

Yes, you can repeat class 12 in the Maharashtra Board after scoring 48% in the science stream. Depending on the board's policies, you may need to retake practical exams. You can opt for either a supplementary exam to clear failed subjects or a marks improvement exam to enhance your scores. Check with your school or the board for specific procedures.

Hope this helps you,

Thank you

Hello,

Yes,When you give an improvement examination in 12th board, the new marksheet will typically mention that it is an improvement examination. It may have a remark stating that it is a Improvement or Second Attempt to differentiate it from the original marksheet. This helps in maintaining transparency and clarity regarding the examination attempts.

Hope this helps you,

Thank you

Hello aspirant,

Yes it is still possible to score good marks in your board exam starting after one month. But it will require your complete dedication and commitment towards studies. As you have not studied till now so you have to make a detailed timetable and strictly follow it. I suggest you to assign more time for difficult subjects.

Thank you

Hope this information helps you.

IIT jee preparation starting from class 12th will be challenging but achievable.since jee covers both 11th and 12th syllabus you need a strong plan to tackle class 11 syllabus quickly while keeping up with class 12th . Try to focus on understanding the concepts of physics Chemistry maths and apply them in problem solving do more and more practice. Using resources like HC Verma for physics, P. Bahadur for chemistry an RD Sharma for math can help to  build a solid foundation. For doubts solving you can take help of your coaching or online resources. Ek weekly test give mock test to know where you stand do analytics of your mock test, identify weak areas and try to improve. Time management is crucial so according to your time table you can manage both 11th and 12th topics you can start doing topics on daily basis. Success with depend on your dedication and consistency. With the disciplined approach cracking the jee starting from class 12th is possible.
