a little bit stress is required for exam , only then u can perform your maximum ,
so, take stress little bit and study for the exam , and also befoire exam attend some of the mock test paper , after attending 3-4 mock test , u will get confidence on how to attend the paper on time , and gradually u will complete it .
frst start with the section that u think u are good at , generally its chemistry , then u can proceed with maths , as maths is directly formula based , keep phy to the last as it demands lateral thinking .
ALL THE BEST ..
