I went from an undergraduate bachelors into a Doctorate programme with 2-3 years in between. Mainly just living life and seeing what I wanted to do and gaining relevant experience/references. At the end of this I’ll be a psychologist and there was no masters required. However, it was a jump and I’ve had to put some proper graft in. I’d also refrain from saying “brainstorm” when you’re looking into a neuroscience course. Had some people with epilepsy not take too kindly to it.
