I have already sent the application form for improvement in three subjects viz. Chemistry, Maths and Physical Education, with the exam fees of Rs. 550. Now I wish to apply for the remaining 2 subjects (Physics and English) as well. What will be the fees for these two subjects? The improvement form states that the fees for improvement in all the 5 subjects is Rs. 600. So do I have to make a DD of Rs. 50?
