Excellent predicted papers

Thoroughly thought through - a lot of the predictions were correct because she had clearly done her research

Biology GCSE - month before exams

The predicted papers were great and help to focus on topics you may be avoiding. These videos on YouTube were so helpful I subscribed to the Member channel to get more detail and work through papers live streaming. They were very, very helpful because they explain so clearly key terms, what the exam board wants to see in your answer and most importantly some common mistakes (so we don’t walk into those traps). Highly recommend all Primrose Kitten downloads and if you follow her checklists, videos and practice questions, and if you are consistent (ie keep doing the work little and often) you will surely get better grades. Her cheerful delivery is also really motivating.

Great predictions and work

The predicted paper serves as great practice for my son's GCSEs. Highly recommend it to anyone giving these exams. Looking forward to using this again for A-levels. Please keep up the excellent work.
