Yes Harshit, you can easily get admission in RCC Institute of Information Technology, Beliaghata for all the branches with your 1730 rank in WBJEE 2018 exam under general category. But as you have a wonderful rank in WBJEE plus a decent score in JEE Mains then you can also try for some of the other government colleges where you have a good probability of getting admission in a good branch like:

• Maulana Abul Kalam Azad University Of Technology, West Bengal
• University Of Calcutta
• University Of Kalyani, Science Instrumentation Centre
• Jalpaiguri Government Engineering College, Jalpaiguri
• Kalyani Government Engineering College, Kalyani, Nadia

Feel free to ask if you have any more queries. All the best!!
