“My daughter did extremely well and had A*s across all her subjects. Keerti is an exceptional tutor and we are extremely grateful for her hard works and dedication. Thank you Keerti.

Mother of IGCSE Student, EdExcel Exam board


'We all thank you enormously for making three difficult subjects great fun while also getting exam results - a brilliant combination!

Mother of twins. One saw their grades go from level 5/6s to level 8 and two level 9s while the other, who is dyslexic, saw their grades go from level 3/4s to level 7s and 8


Pleased to report J got a B in Physics and a C in Biology.

He was so much more confident in Physics he was slightly disappointed it wasn’t an A!  All down to your work with him and giving him that extra boost. And he thought he was likely to fail Biology as he had not fully covered the curriculum. So many thanks for your help!'

Who's behind The Extraordinaries Club?

That would be me!

My name is Lucy Parsons. At school I developed a study system that earned me five As at A level and a place at Cambridge University. I taught geography in secondary schools for four years and now coach students in exam skills. I am also the author of The Ten Step Guide to Acing Every Exam You Ever Take.


Being a member of The Extraordinaries Club has given my daughter a massive boost in confidence and improved her wellbeing hugely. She is really motivated and is feeling good - a very different place to where she started only three months ago.

The Extraordinaries Club is a great way to get more in-depth, personalised help in the form of workshops, coaching calls, chat forums and specific topics. Both students and parents are supported on how to survive the exam years. Highly recommended if you want to help your child achieve their potential while retaining your sanity!”

Working with Lucy I learned to manage my time, stay focused and prioritise. Lucy helped me not only to get the most of academic life, but to improve my leisture time too. I learned how to keep calm and be completely in control of my workload all year round. I will use the techniques she taught me far into the future, and some well beyond the classroom.

Have questions? The answer might be here...

Is this masterclass for parents and students?

This masterclass is primarily for students, as they're the ones who need this information to improve their A Level Chemistry revision technique. However, if parents want to join for moral support you're very welcome. 

Is this masterclass suitable for my exam board?

This masterclass will help students following all A-Level specifications including AQA, OCR and Edexcel (Pearson). 

What’s the point of the masterclass if exams have been cancelled?

Exams in their normal form may have been ‘cancelled’ for year 13s but some form of assessment is still going to take place and the grades awarded this summer will be dependent on how well you do in the assessments.

In the topics that students are assessed on, exam boards are still going to be wanting students to demonstrate that they have:

  • The depth of knowledge and understanding that someone would normally have to get a specific grade

  • They have the thinking and communication skills (what we’d call exam technique) to get a specific grade

So, it’s still very much worth students in year 13 getting fully up to speed with their A-Level biology revision and study skills.

For year 12s, we have to assume that exams will go ahead next year in their normal form. So, the sooner you develop the study and revision skills you’ll learn in this masterclass the more ready you’ll be for next year’s exams, with way less stress because you’ve been doing it right all along.

If I sign up for the masterclass will I be signing up for a recurring subscription to The Extraordinaries Club?

Only if you sign-up for a monthly recurring subscription (£64), which you can pause or cancel at any time. If you sign-up for the 1 month limited membership (£75) you will only make one payment and your access to the masterclass, as well as the rest of The Extraordinaries Club, will expire after 31 days. However, if you like the club and choose to upgrade to ongoing membership you can do that on your account page. If you choose not to, then your access to the club will expire after 1 month of membership. During your month of membership you will have all the same benefits as members on recurring subscriptions e.g. the ability to set up five sub-accounts for members of your family, participation in the live coaching calls and access to all the other resources and masterclasses on other subjects inside.

Can I sign-up for The Extraordinaries Club directly?

Yes! You'd be welcome to. This way you'll get access to all the other workshops I'm running through the year and you won't have to worry about signing up, as well as all the modules teaching study skills inside the club. Up to five members of your family can have their own log-ins to the club for one monthly membership fee. Click here to join The Extraordinaries Club on a recurring subscription.
