M.Sc

Of course, an online programme in MSc Interior Design is apt for students who wish to get a degree in this field but are not able to opt for a regular on-campus course. It will offer them great flexibility, affordability, and industry recognition.
An online degree course also provides relevant knowledge and skills as a regular program, if you choose the right college.

For the practical exposure, the MSc Interior Design curriculum includes some lab subjects like CAD (Computer-Aided Design), model-making, and materials exploration. These subjects help students get their hands on Design Software, construction, model-making, etc. Many Design colleges have their labs specifically designed to provide an environment where students can explore their creative potential.

The difficulty of an entrance exam depends on its nature and not on the specific course. A single entrance exam can be conducted for many course admissions. For instance, the CUET-PG exam is conducted for many course specializations and fields; hence, its General Test and Aptitude Section are the same for every course, however the domain-specific section has the course-related questions. 
Meanwhile, the entrance exams for the MSc in Interior Design can be a bit-competitive based on the course level and the field.

It depends from college to college, not every MSc Interior Design college requires candidates to sit an exam, some provide admissions based on the merit score. Some top Design colleges like INSD Pune, AAFT, JD Institute of Fashion Technology, etc., offer admission to MSc Interior Design courses on the merit system.

The MSc in Interior Design is a postgraduate degree program, hence, it lasts for 2 years as every PG degree program. However, the duration for online or distance programs may vary.

Here are some important things you must carry during the MSc Interior Design application process to ensure a seamless admission process:

• Class 10 and 12 marksheets
• A relevant bachelor's degree
• Valid ID Proof (Adhaar, PAN Card, Passport, etc.)
• Passport-sized photographs
• Migration Certificate
• Entrance exam score (if any)
• Portfolio (if required)

Carry both the original and hard copies of your documents.

Pursuing an MSc in Interior Design course will help you gain many skills important to succeed in the field:

• It will teach you about the technical part of Interior Designing, such as how to use Design software, material knowledge, sketching, etc.
• It will also help you develop in the professional front, like communication skills, networking skills, portfolio making, and so on.
• Lastly, the core Design skills are an obvious part of the programme to teach you everything about the Design field in-depth.

An MSc Interior Design and an MDes Interior Design differ based on their curriculum focus. MSc Interior Design is more focused on the research part of the field; however, the MDes is inclined toward the creativity and functionality aspects of Interior Designing. Now, which option is better is a subjective question, and its answer can vary from person to person. 
In my opinion, I would go for MDes in Interior Design in terms of job prospects, skills development, and industry exposure.
