SAP

SAP is a business software package designed to integrate ll business areas including quality control. In CATIA, you can not only create a car but a factory in which it will be produced, the machining processes required and even you can simulate ergonomics studies as well, like weather the current layout of a plant will be comfortable for workers to work or not.
So, you can simulate the whole thing within a virtual reality including and of course rendering. SolidWorks is purely a product to design machines. Of course, there are other applications like aerospace, automobile, consumer products, etc. Much user friendly than the former one, in terms of modeling, editing designs, creating mechanisms, etc. One can explain like this. Create an aircraft in CATIA but create the engine in SolidWorks. Choice of application depends on your area of work.

Please visit the above link for the syllabus and academic structure for MBA course in Christ. First trimester any student would feel little hectic, as this is a professional course where you'll have to manage your academics, current affairs knowledge, extra curricular activities and other assignments. Gradually you'll understand how to best manage your time and the course shapes your overall personality development.
Yes, SAP certification is provided free for some specialisations like LOS, whereas others have a chance to take up the course apart from the academic curriculum.

Certification holds the key for any professional course. It is the ultimate testimonial for the knowledge acquired on any subject. Now the certification cannot be issued by all. The desired value can only be achieved from certificates issued by proper authority. Just erase the University logo from your graduation certificate and you will understand the difference.
In the field of SAP consulting, the only authority to issue such certificates is SAP itself. They design courses and deliver them through their authorized education partners. SAP is a global entity and runs its courses all across geography. Hence, it has a global acceptance and known as Global Certificate. It is the ultimate benchmark for the skills and knowledge acquired on any specific SAP module. Certificates issued by any other entity is of absolutely no value.
From the employment perspective, the main employers to SAP consultants are IT consulting companies like:
1. TCS.
2. Capgemini.
3. Wipro.
4. HCL.
5. Deloitte, etc.
All these companies deal with foreign clients, who are very particular about quality of delivery. Hence, they all put emphasis on SAP Global Certification as it is the global benchmark and is accepted by all. So, chances of getting a job without SAP Certification, doesn't exist. The course fees is relatively higher, but it is a one time investment that one makes and fetches the benefits for rest of their entire professional career.
JKT is an organization, which comes under the brand of JK Group (JK Tyre, Cement, Papers, Seeds, Raymond etc.). It is associated with SAP for past 2 decades and is the oldest education partner of SAP in Kolkata and East. Hence, my suggestion would always be to go with JKT.
