There are tons of very well-done professional level video courses on Youtube.
There are more organized courses that only ask you for money for the "extras", like some tests and a certificate, but the main parts, texts and videos, are free.
You could start with a really good teaching professor (Eric Lander, MIT) and his course: https://www.edx.org/learn/biology/massachusetts-institute-of... (the "Audit" track is free, ignore the prices; also ignore the "expires" - this course restarts every few months and has been available in new versions for many years now)
It's very engaging!
There's similar courses for everything in the life sciences, there on edX, on Youtube, many other places.
I feel the true Internet is soooo underutilized by most people! Forget news sites, opinion blogs, or social media. Knowledge is there for the taking, free. Only the organized stuff, where you end up with a certificate costs money, but they usually still provide the actual content for free.
Whether or not broad support for training scientists holds up during and after the current administration remains to be seen.
Work for a company that will pay for it.
I encourage people to look into it, it's a benefit a lot of people have but don't use and it's leaving money on the table.
1. Masters degree only, they won't pay for anyone to get a bachelor's or associates
2. Must maintain a B average or better
3. Cannot take any time off, it has to be entirely on nights and weekends
4. Reimbursement after the fact, so you're taking on the initial financial risk up front.
However, to use it there are constraints: 1. The topic should be related to technologies used by company. Cannot get a Google cloud certification as they are using aws. 2. To get it you need approval by line manager, hr, and director of the office. 3. If it is more than €250 you need to sign up loyalty agreement for a year. Meaning if you will return some amount of you quit.
With all that strings attached it is just a marketing bullshit to attract new hires.
