Today I am in lovely London at @imperialcollegeldn.bsky.social for the second Year 13 Further mA*ths masterclass. Today I get to talk about problem solving and ask "what is X anyway?"

After a v tricky 2025 I went back to the gym in December. I have been consistently going 4 times a week to PT & today I braved a run. I started running after my daughter was born in 2010 and loved it. But the last few years the weight has piled on and the knees can't take it. Today I did this 😍

Car insurance feels like one massive fraud at the moment.

We are now being charged an extra £300 (on an already ££££££ policy for a 17 year old) because the "purchase date" they asked for was apparently not the purchase date.

Exhausted with fighting this stuff!

My son did. They only go in to college when they have an exam and the rest they can study at home or college or go to some optional/not optional study sessions.

Preparing for the TMUA (Test of Mathematics for University Admission) This on demand course offers specialist tuition to support students preparing for the TMUA (Test of Mathematics for University Admission).

With @ox.ac.uk and @cam.ac.uk Maths courses now requiring TMUA for 2027 entry onwards it seemed a good time to remind you of the @meimaths.bsky.social TMUA On Demand course. Free for students from state-funded schools & colleges. Perfect to recommend to Year 12 students 😁

Portrait of Mikaela Iacobelli, an associate professor, smiling at the camera. She has shoulder-length light brown hair and is wearing small stud earrings and a navy blue top. The background behind her is a soft light blue. The overall graphic features a slate-blue backdrop with the β€œHMS – Her Maths Story” logo centered at the top. Her headshot is framed in the middle, and below it, on a torn-paper style white overlay, her name β€œMikaela Iacobelli” appears in large black text, with β€œAssociate Professor” written underneath in smaller capital letters.

Absolutely the same. That single Mum NQT year was absolutely something else but this year my baby is 25 and he makes the world a better place ❀️

I feel like it was a struggle and a cheat code. I couldn't not do my absolute best when every minute I was in lectures or studying was time away from my boy. I feel incredibly lucky to have him inspire me to be better but also my goodness degrees/PGCEs are hard when juggling children as well!

This one time I had a baby at uni. Today he got his last exam results at uni (he has a 60 credit dissertation to go) and they included 99% in Quantum Computing! I can't wait to recreate this photo at his graduation in July. How wonderful life is with him in the world 😍
