Well, I have personally tried the Scalar data science & machine learning program. It’s definitely good, I have to say. With live classes, they have one-on-one mentorship, industry projects and help in finding jobs as well. Plus I have seen students' ratings for their data science programs, they are impressive. All in all, it is as good as it seems, but there are a lot of other things to know.
Data science is already one of the best courses given current times. If you don’t know, LinkedIn named data science the fastest-growing job in 2k17 and it has been almost the same for all these years. Scalar of nor, doing a data science course now is most relevant. Plus data science professionals earn crazy money. Just in the USA, you can expect a six-figure salary in your mid-career.
Scalar is a good source for online studies. In India, it is very popular. I have seen many students that ask about their data science course and how good they are. Be assured for an online course it is very good. Plus these kinds of courses don't cost much. You can do a six-month-long course of like 2-3 lakhs. These courses are efficient and help to land a job in data science.
However good it may be or sounds, I would not recommend it as a general option. See, the best jobs and careers in data science are located in prime locations. There are MNCs and many government bodies that have a high demand for data scientists. Leaving out all the best options just to maintain an easier and cheaper course is not something you should do. Scaler is a good doubt, but you have to target a full-time data science program.
There are hundreds of top-tier universities in the USA, UK, Canada etc. They have many courses in data science that are a big attraction for international students. Just from India, more than a million students go to universities abroad for their higher studies. You can target these ones based on your academics.
These full-time courses allow you to apply for bigger jobs. Plus, after graduation, you can stay back and work in the selected country where data science is popular. Not only will you earn more, but you can also work in more areas and locations. If you need help on how to start, let me know. Happy to help anytime.
