Quicker way to learn Russian?

Hi all, i am Rahul and i am a student from Mumbai, India. I recently finished my high school and want to pursue my career in engineering. I want to go to Russia for my further study because my uncle and aunt lives there and they want me to go there live with them. I have already applied to the college i will be going to but i need to learn the language. I could just go there and start learning there but i thought it would be better if i have some preparation from here. I found a course by EchoEE for learning the language much quicker, the description says so. What do you think guys, i want to know what process is best for learning the language much faster. I am going to Russian in 3 months now.
