The branch change policy of IIT Patna is very much similar to that of other new IITs except for a few changes. Here, the students change their branch after the 2nd semester. The eligibility criteria for branch change at IIT Patna are as follows 

• You should have CPI greater than or equal to 8.0 to be eligible for branch change 
• All the 1st and 2nd-semester courses should have been cleared in the first attempt.
• In case of a tie, the JEE rank of the applicants will be considered
• The total batch size after all the changes cannot change by more than 10% lower or higher.

IIT Patna invites applications for branch change after 2nd semester and students are ranked on the basis of their CPI. 

The PG programs offered by IIT Patna are decent so it is recommended to do your MTech from here. Here are a few highlights of the program

• PG programs at IIT Patna are offered in the following branches CSE, Communications Engineering, Mechanical Engineering, Nanotechnology, etc.
• The faculty of the PG-level programs are more than adequate and experienced in their respective fields.
• The course structure is challenging and is at par with top IITs like IIT Bombay, NUS, IISc, etc.
•  The final year research project provides great opportunities to explore multiple fields and choose the one that aligns with your career prospects.
• IIT Patna MTech placements are great and during IIT Patna Placements 202286.81% of the M.Tech batch were placed. IIT Patna MTech's average salary stood at INR 14.99 LPA. Top branches like Computer science and engineering, mathematics, computing, VLSI/Embedded systems, and mechanical engineering secured 100% placement rates and the overall placement percentage of MTech was 86.81%.

So, IIT Patna is a great choice for MTech in any field. 

I refuse to believe that the new IITs are less preferred by students considering their exponential growth and achievements. I don’t think that the new IITs are lacking in any way be it the campus or the placements. Most new IITs are now operating from their own modern campus with top-notch infrastructure. The average packages of the new IITs again prove that they are nowhere inferior. 

The reason why some are preferred over others is simply because of location. Initially, Andhra Pradesh had the maximum number of selections in JEE so the IIT Hyderabad's opening and closing rank was better than other new IITs. Also, Hyderabad enjoys a better location than Indore. Personally, I believe if you are able to make it into the new IITs then getting old IITs isn’t difficult either. This proved that the new IITs are doing well and aren’t lacking in any aspect.

IIT Patna MTech placements recorded 100% placements for the Mathematics and Computing branch this year. The average package for MTech MNC at IIT Patna stood at INR 15 LPA. However, I feel one should look beyond placements while evaluating the worth and credibility of a program. It's good to consider the achievements of the students who have completed the program. That being said, IIT Patna MnC students' achievements have been listed below 

• Many students of this branch got selected for DAAD IIT Master Sandwich Programme
• Some have made major contributions to research as well as in the Industrial area.
• A few get the chance to pursue higher studies from top Foreign and Indian Universities such as the University of Dallas, USA. 
• Some even contribute to the government sector.
• The students of this branch have been securing the highest CPI among all branches of Mtech.

So, it’s best to look at the bigger picture and consider all aspects rather than just considering the placements for choosing a branch.

Recently, IIT Patna has changed Electrical Engineering to Electrical and Electronics Engineering. Even before this, the Curriculum of the course was Electrical and Electronics(EEE), only the change in name has been done.

IIT Patna Electrical Engineering is one of the oldest branches of the institute and has the most experienced faculty pool. Many professors are members of various International forums such as IEEE. The EE department is known to publish many papers and works on various government and private-funded projects.

IIT Patna EEE has the best curriculum and culture because of its 

• Fully equipped world-class research labs of Embedded systems, VLSI, Broad Communication and Networking, DSP Labs, RF and Microwave labs, Advanced EE labs, and Electrical Machines Instrumentation
• Collaboration with foreign Universities for student exchange programs such as National University of Singapore(NUS), and Kyoto University. 
• Excellent placement scenario of IIT Patna EE with the highest CTC standing at INR 82.05 LPA and the average at INR 24.85 LPA. The placement percentage of this branch is 83.56%. Students usually get placed in RNDs, PSU’s, IT sectors, etc.
• Big achievements made by the students such as participation in ACM-ICPC World Finals and being the top in DD Robocon Stage I.
• The alumni of the EE department of IIT Patna aced the Civil Services Examination like IAS, IES, etc. One of them secured AIR 33, while the other secured AIR 64. 

Overall, the IIT Patna Engineering department is well-regarded and is a great choice.
