Anybody knows where I can take online courses related to my field, like chemical engineering? I graduated 3 years ago and only have 5 months of experience. After that, I worked in a different sector that is not related to my field. Now I want to get back to my profession but it’s becoming difficult to find a job because I’m neither a fresh graduate nor someone with enough work experience. So I think taking courses and getting certificates might help me. Do you have any ideas or know any places where I can take those courses?
