Chemical engineering is the application of the principles of physical sciences together with the principles of economics and human relations to fields that pertain directly to processes and process equipments in which matter is treated to effect a change of state, energy content or composition. In Layman words it is concerned with the transformation of raw materials into useful products making use of chemical conversions and physical operations. The chemical engineers use the technologies developed by the chemists in laboratories for the commercial production of a wide variety of materials. Chemical engineers must develop, design and engineer both the complete process and the equipment used, choose the proper raw materials, operate the plant efficiently, safely and economically and see that the products are up to the standards of the consumers.
Chemical engineering is not chemistry alone. Along with chemistry a sound knowledge mechanics, physics and mathematics are must. A +2 student opting chemical engineering must have a good aptitude for solving problems. He or she must have a good base in stoichiometry (a must), kinetics and physics. Along with the knowledge the students should take it as their career option if they have an interest towards it or else the subjects become quite dry. Some of the main subjects that students have to learn during the course are stoichiometry and process calculations, heat transfer operations, mass transfer operations, chemical reaction engineering, chemical thermodynamics, process design, process control system, optimization etc. During the course we can see many subjects that we have in common with mechanical engineering. But the major difference is that we are more interested in the reactions that takes place inside the reactors, the conversion yields etc. A common fear that the work conditions of chemical engineers are hazardous is a fluke. Chemical engineers work in safe environment and direct contact with chemicals is minimum.

Have you ever been to a factory or industry? Have you seen a factory or industry in television? Have you ever thought how the whole system works efficiently? Who has planned and implemented the whole system, selected the technology, machines and the amount of materials? Well the answer is production engineer. Without a production engineer a company may never operate efficiently. An entire production cycle consists of planning, procurement of materials, managing, manufacturing, distribution and sales. A production engineer plays a major role in all sections except distribution and sales.
Production engineering is some what similar to mechanical engineering. Almost half the subjects are same for both courses. The difference is that production engineering has an upper hand in management side and manufacturing side. Manufacturing subjects gives you knowledge about machining processes (milling, drilling etc), joining processes (welding, soldering etc), castings (die, sand etc), metal cutting and tool design, machine tools, automation, assembly lines, jigs and fixtures etc. Management subjects makes you strong in ergonomics, manufacturing management, materials management, production planning etc. And therefore production engineering is a combination of manufacturing technology and management techniques. During your engineering course, final semesters mainly consists of management subjects. You can get mechanical equivalent certificate by just writing a test.

I know many students who love biology and took bio-maths during their high school. But unfortunately because of financial problems couldn't opt medicine because the tuition fee for medicine is too high compared with engineering unless you get scholarship through entrance examination. Well If you still have that desire but you are opting engineering then this is the right course for you.
Bio-medical engineering is among different courses of engineering. It is basically engineering in medicine. The statistics of course is 75% electronics and 25% medicine. Bio-medical engineer deals with the sales and services of medical equipments and developing health care devices and procedures that has a solution to medical and health problems by combining engineering principles and techniques in medicine field and biology. What is its scope??
In school did you have a liking towards resistors, transistors, diodes in physics lab. Did you ever have a liking towards chips of computers or other electronic device or mainly did you have a liking towards electronic devices. Have you ever wondered who configures a television or a computer. Due you wish to know more about different forms of communication , robotics, signal processing etc then electronics and communication is the right course for you.
Electronics and communication or EC is a branch of engineering which deals with study of electronic equipments which we use in our daily life and about communication such as radio, mobile etc. The content is more in the communication side than the electronics side. An electronics engineer deals with the fabrication of IC's and its components such as resistors, transistors etc. I will explain with an example the difference between an electrical engineer and an electronic engineer. An electrical engineer does the wiring of a television but it is an EC engineer who configures the television. I hope you understood the difference.
Almost all EC students tells that EC is a dry course full of theory. My EC batch-mates told me the same thing and i don't see them out of their classrooms. The syllabus is pretty difficult compared to other branches. The syllabus has a lot of maths, a bulk of equations, a lot of programming etc and so if you are not good in maths or equations then this is definitely not the course for you. Each semester has atleast 1 lab and i have heard that the lab exams are difficult (depends on the college). I have seen my friends disappointed after lab exams and they say that they didn't get the output result. I am saying all this because a lot of students take courses just because there is a vacant seat. Take this course only if you like electronics. If you are interested then i don't think the course going to be that difficult. What is its scope??
During childhood everyone would have ran out of your house to glance up the sky to see an airplane or helicopter as soon as you hear its sound. You must have thought how this thing is flying as a bird or who made this thing. You might have thought of making an airplane and might have made with a paper. You might have bought a flying plane that is operated by a remote controller. You would have opened the toy just to know how it works. Well, If you still desire to make an airplane and If you wish to open a real airplane to know its mechanism aeronautical engineering is the right course for you.
Aeronautical engineering is the study of how plane (all kinds) fly within the earths atmosphere and to apply all that knowledge to design, build parts and to assemble them into aircrafts and also missiles. Mainly aeronautical engineering teaches about aerodynamics (effect of air on solid bodies), avionics (design of aircrafts), propulsion (force required for flying a body), material science (selecting light material that can withstand large amount of force), structural analysis (for stability) and manufacturing (techniques).
Development and manufacturing of a modern or a new flight is a too complex and expensive process. For that you should have knowledge in this field, must be skillful, creative and should know about latest flight technologies. Main areas of focus are testing, maintenance of aircrafts and missiles, fuel and system analysis, dangers of aircrafts, its effect on environment etc. You should be good in maths and you have to study electronics, software design, risk analysis etc.
I will mention the subjects (not all) that you have to study during the course- Material Science and Engineering, Thermodynamics, Manufacturing Processes, Advanced engineering mathematics, Instrumentation and Control Engineering. Fluid Mechanics, Theory of Machines, Aircraft Materials, Machine Design, Vibration Engineering, Heat Transfer, Aircraft System, Aircraft Structure, Propulsion, Reliability and Maintenance Engineering, Fatigue and Fracture, Total Quality Management, Aerodynamics, Aircraft Design, Maintenance of Power Plant System, Helicopter Theory, Aircraft Communication and Navigation, Civil Aviation and Regulation, etc. I have written previously on scope of aeronautical engineering.
