Here are some courses mentioned-
1. Computer Courses: Basic computer knowledge with an average typing speed is a must to obtain any job in these days. The computer has become an essential part of our life and one who is unaware of the basics of the computer will be pushed back by other candidates. For a commerce student, minimal computer knowledge will be enough. You may attend courses on Microsoft Office (MS Word, MS Excel, MS Access (SQL) and MS Power Point). Among these MS Excel and MS Access will turn out to be important. Still, there are many calculations and information stored in MS Excel by organizations, hence a thorough knowledge of it is a must.
2. Accounting Software: Gone are the days of bookkeeping. Now everything is stored in a system and to make it much easier, accounting software was developed. There are many popular accounting software such as Tally, Peach Tree etc. An organisation can develop customized software also. If you are commerce graduate or postgraduate and would want to have a strong career in the accounting field, then you must learn any of the accounting software and must obtain a certificate from an approved institution. The important accounting software normally used by companies are Tally, Peach Tree, QuickBooks Pro, MYOB Business Essentials Accounting Software, etc. Always make sure to learn the latest version of the selected accounting software.
3. SAP/ERP: SAP Enterprise Software is used only be few companies, especially by MNCs. ERP (Enterprise Resource Planning) is another term we hear these days. Yes, these two concepts are of great importance and a person with knowledge of these two can get better job opportunities. There are not many who have done this course, hence your chances are more. The duration of the course varies from 45 days to three months.
4. Advanced Certificate Course: SHRM (Strategic Human Resources Management) India, Carlton Advanced Management Institute, The Indian Institute of Technology (IIT), Bombay, Sales and Marketing Executives International (SMEI) etc. are some of the establishments that offer good and authenticated certificate courses for commerce students. If you are looking for an advanced certified course in the field of finance, then you may go for Certified Financial Planner Course (CFP).

Hi Shweta, Here are the key differences between the two:
Certificate course:
A certificate course teaches students the basics of improving the functionality and attractiveness of interior spaces. The curriculum focuses on the use of fabric, color, lighting, space, furniture and accessories in residential and commercial interiors. Many certificate programs are not accredited by professional organizations and hence do not have much market value. Diploma course:
A Diploma programme covers both the fundamentals of interior decorating and the technical aspects of design. Students learn many of the same topics that are covered in certificate programs along with other intensive practical training. Completion of an internship or portfolio project may be part of the Diploma requirements. The market value of the Diploma is much higher than a certificate course, provided it is a regular course.
