My DS is just starting 4th year of a BSc at Liverpool. He has just completed a placement year out, but in a specialised field unrelated to Chemistry (allowed for a bachelors degree, but not masters)
What shocked us, however, when he was applying for Placements two years ago, was how little help the uni gave (just pointed them to websites that all students in the country can access!) and how hard it was to even get interviews.
As well as the speciality placement he accepted, he also applied for some in Chemistry and did get some interviews, but most of his friends had given up looking by Christmas due to lack of success. These were kids with good A levels, some of whom got a first this summer.
He said about 50 out of 100+ students in his year started applying for placement jobs, but he was one of only about 10 who were actually successful. 1 of his year got into Glaxo, none of the rest were even interviewed, similar with companies like AstraZeneca.
One of his school friends, doing Chemistry at Birmingham, also had no luck until the very end of the academic year (think he was offered something in the June/July). The problem with holding on for an offer that long, is that if they don’t get a placement, they need to sort accommodation for the following academic year, preferably earlier than June/July!!
So, my advice would be to research how many students do a placement each year at his chosen unis, and how much help do the faculty give them in getting those placements.
I remember going to the Liverpool open day with DS - there were slides about placements and how many different companies/countries they could go. They made it sound so easy to go to a big company or even abroad. But it’s not like that in reality unless the uni has links with particular companies/industries.
