I am in 2nd year civil engineering at NIT Jamshedpur. What is the right time to prepare for the IES?

One of my friends completed his BTech in civil engineering from NIT Jamshedpur recently. He also cleared the ESE in the final year by preparing for the 2nd year. All he did was devote around 5–6 hours a day for the next two years daily. 

Here also mentored the following tips:

• Get the study materials for non-technical from any coaching institute and study them for an hour daily.
• Start with one subject at a time, most likely Math because it will help you for GATE preparation.
• For the technical papers, refer to handwritten notes of any coaching institute or refer to correspondence course materials
• Make a small group of 2-3 students in your hostel so that you are continuously encouraged. Set targets for the group to achieve and work hard.
• Monitor your process and keep a check on distractions. 
• Utilize all the free time to study because civil students have a very light curriculum and so are free most of the time.
• Practice as much as you can.

Hope the above tips will help you clear IES!
