I am currently finishing my third year in Electrical and Electronics Engineering. What can I do other than working on my CGPA to increase my chances of getting into a good college? If you guys have any tips specific to MS in Robotics it would be very helpful. My dream colleges are CMU and Colombia but they seem impossible now:( CGPA:5.9 GRE:330 TOEFL:100
