Hello Aspirant ,

No , you can not increase your marks in class 10 by giving money or bribing the exam authorities as it is illegal ,you can be rejected from giving any exams in future plus you can even be jailed or liable for a fine .

Even if your school is telling you that they can increase your marks do not accept it and pay them the money , you should just accept your result and try to be better in future and improve yourself .

Hope this helps.
