For the first year of my PhD journey, I have attended 2 courses and 2 workshops. I had to. Attending workshops increase my learning process and cut short the time I need to spend if I had to do it on my own. It also decreases the risk of making mistakes in the actual study.
Being a PhD student, I believe we need to be a specialist in a subject and at the same time a generalist in all sort of things. You need to have the technical skills, emotional skills, interpersonal skills, intrapersonal skills, management skills and other sorts of skills.
Here are the courses’ and workshops’ materials that I have attended that might be of your interest. I would be happy to share my knowledge. The more you give the more you shall receive. InshaAllah.
Good luck in your study and please pray for my success too.
