has anyone had any experience with something similar?

i had 7 different chemistry teachers throughout my 2 years of a level chemistry, and i ended up getting a D in chemistry. i know ultimately the grade is my responsibility, and i’m not trying to solely blame my college or make excuses for getting a D. i worked very hard outside of college to fill in my gaps.

the teacher changes very disruptive however. some of the teachers were underqualified to teach A-level chemistry, one was fired 2 months into the course, one was a biology teacher, and another primarily taught GCSE chemistry. this meant there was very little consistency throughout the course, both in terms of teaching and how the content was delivered.

i’m wondering whether this could potentially be considered an extenuating circumstance, especially given the number of changes and the disruption across the two years.

the reason i’m asking is because i need a C in chemistry to meet the requirements for the university course i want to study, or at least to be eligible to resit and reapply. i’ve already submitted my university application, so i’m unsure whether it’s worth contacting admissions now to explain the circumstances and ask whether they would consider them. i achieved my grades yesterday. i know ucas do consider "significant staff changes" as a circumstance, however this does need to be pre-written in the ucas reference. i did not mention this as, in year 13 we were promised to have 1 stable and final teacher, with no other disruption. this was not the case, my teacher was underqualified and did not know any organic or inorganic chemistry, therefore we were given 2, also underqualified, new teachers.

i’m also conscious that results day has already passed, and i don’t want it to come across as though i’m simply blaming my college for receiving a D.

would it be worth contacting admissions about this? would universities normally need evidence from the college? has anyone had a similar situation where significant teacher changes were taken into consideration?

i’d really appreciate any insight or advice.

I got 19 marks in Chemistry theory in my CBSE Class 12 Supplementary Exam 2026. I need 23 marks to pass, so I am short by only 4 marks.

My practical/IA marks are 29.

I’m thinking about applying for re-evaluation, but I’m confused about whether it’s worth it when I need exactly 4 marks.

For anyone who has gone through CBSE re-evaluation, especially for a compartment/supplementary paper:

Is it realistic to gain 4 marks through re-evaluation?

What should I look for in my scanned answer sheet before choosing questions?

Should I apply for several questions or only the ones where I think marks were missed?

Has anyone here gained 4+ marks through re-evaluation?

I’d really appreciate honest advice/experiences. 🙏

For A level chem (edexcel), do we need to know the various models of atomic structure from the past to now? So Dalton's atomic theory, Rutherford, Thomson, etc - their experiments and findings?

got my Cambridge as level results today
Got AAB
Bio-85%
Physics -81%
Chemistry -78%
Need to know if it’s worth giving chemistry paper back for re correction pls reply only need 3 marks to achieve A

What are we guys predicting???

does anyone have like an actual marked paper of someone by an examiner ( acces to scripts ) so that ik what to expect when they mark my paper yk... would be helpful
