JGM - Work experience

A few weeks ago I posted about the agency JGM who I have gained as a contact for work experience. When I last spoke to them they weren't sure on dates that I could come in as of a tight workspace and office areas full. But I got an email this week to ask if I could get back in to contact to suit dates, which is what I did today. I rang my contact, discussing dates and they suggested next week (7th April) but I am on another placement at this point. I proposed the week after maybe, he then explained I would probably come in Thursdays & Fridays each week so it ended as he is going to email dates that are available and depending on University sessions  or time off we shall go from there.
