I got a GMR 865 in Wbjee 2020 and TFW rank 78. Can I get ECE or Electrical engineering in Jadavpur University?

First of all congratulations for your result. The cutoffs change every year as it depends on various factors, but you have a good rank so you can expect a good Engineering college. Based on your rank and going by last few years' data, it might be difficult to get Electrical Engineering in Jadavpur University as after round 3 of counselling, the last rank to enter the college in Electrical Engineering lies around 640 GMR through TFW quota. But the branches based on your rank in TFW you can expect, Mechanical Engineering, Electronics and Instrumentation Engineering, Chemical engineering, Civil Engineering, Production, Metallurgical, Construction Technology, Power Engineering, Printing Engineering, Food technology and Bio Chemical Engineering. However, this is based on last few years' cutoff and this year it might get changed. But you can get into Jadavpur University, may not be Electrical but other branches mentioned above can be achievable. You can use our WBJee college Predictor tool to know where you have good chances
