Hello aspirant.

Don't be discouraged. You still have another year. You need to study hard and try your best. If you study at least 4 hours a day, veiw previous questions and solve materials of coaching Institutes, you can easily crack jee and get an iit. 

All the best

You have to study with full concentration, no disturbance, and continuously for 3 hour sessions. The idea is to simulate real exam conditions. While studying, you have to create an atmosphere as if you are sitting in exam. Avoid doing following during a 3 hours session:

• Study on a desk if you have it at home. Avoid studying while lying down on a bed.
• Don’t get up from your desk during 3 hours of study session. Even not for drinking water.
• Don’t listen music during studies. If you have a habit, then slowly come out of it by reducing it day by day.
• No phone calls and no SMS during studies.

Your sincerity and dedication can only help you to acheive your motto.
