Mechanical Engineering

First of all, congratulations for your results.
Hope you are doing well. As you concern about the branch you can get in the MBM Jodhpur. So, all the branches are good. But you should go according to interest. If the field doesn't matter then go for electrical engineering through which you can get an opportunity for getting a job in private and government sectors as well.
All the best.

Yes, you can.

Hi Krishna,Please refer to the link provided below for a detailed comparison between SVS College of Engineering Coimbatore & SJC Institute of Technology, Chikkaballapur for a course. https://www.shiksha.com/resources/college-comparison-247530-189965
You should be able to compare various features of the two institutes to help you reach a decision of which is better, and where you would like to pursue. Regards.

Dear Charles, there is no age for learning. So, its okay if you have 3 years gap. Submit gap certificate and take admission. You can appear for LEET exam or go for university specific exams or even go for direct admission subject to fulfilling the eligibility criteria. Universities like LPU, DIT, Mangalyatan, Chitkara, etc. Are offering B.Tech Lateral entry. All these universities have wonderful infrastructure and world-class facilities to offer to students apart from good placements. Some even offer scholarships to meritorious students. Good luck.

Hello Chetan,
It's indeed very good to hear that you have already set your aim. Congratulations. For achieving this, you need to pass 12th with good marks. Then pass CET of your state or JEE or CET's of deemed universities with good ranking. Better the rank, better are the chances of getting what you want. One advise, please study to learn the subject and not to obtain marks. Marks will automatically flow.

Hi,
Flinders has a better ranking as compared to CQ.

Both are similar in comparison. Both these colleges fall under top NIT category. So we can't say like which one is better. Yeah from campus life and location point of view, NITK is better than any top NITs.

I would suggest you take CSE in SVNIT. In terms of placements also, CSE is better than mechanical in any college.

First, try for IITs and NITs by appearing for JEE. Next, look for state government and central government colleges. Finally, you can look for private colleges like Manipal, SRM and VIT.
