Such useful advice!! Especially the bit about using your summers wisely. I found that volunteering abroad during my summer in Sri Lanka on a Mental Health placement (with SLV) was such a great way to not only do something worthwhile with my spare time but also I think it really helped me to stand out from other applicants when I was applying to my Master's courses here in the UK (equivalent to Grad School) as I was really struggling to find relevant experience to with Psychology and Mental Health. Best thing I've ever done!
