YOUR Chemistry Studies in 2020-21. Take Action. Take Charge


What happened?

Here’s the reality that families, and students have faced, and will continue to face in the near future. The 2019-20 academic year ended in the midst of a global pandemic, and in chaos. Frankly, 2020-21 will likely be just as disorganized, just as disjointed, and just as messy, with the chemistry education of literally millions of students being grossly disrupted, and placed in jeopardy via hybrid and online only schedules. The only thing that is certain is that student’s chemistry education will be suffering.


What can you do?

In two words, “seek help”. That help may be sought for many different reasons, and be in a number of different forms. Perhaps to simply keep a students’ head above water in a disrupted, hybrid school year; maybe to maintain that stellar GPA, and to protect the precious path to college; perhaps to ensure that a SAT Subject Test, or AP Exam score ultimately reflect the true academic ability of the student; or simply to help fill the gaps in the preparation for tests at school that this year will inevitably bring.

How does it work?

I can provide everything from simple, remote one-on-one tutoring, through to a much more comprehensive plan, including specific, tailor-made strategies, and materials. It should be noted that remote tutoring is NOT a new thing for me, hastily cobbled together to adapt to the current circumstances, rather it has been my preferred method of operation for close to a decade. If you’re concerned about what ‘school’ will look like in 2020-21, and want to safeguard your chemistry education then let’s start the conversation.

Chemistry Tutoring

Many students find their chemistry classes challenging ones. Reasons include the intellectual demands of the subject, difficulties with the mathematical aspects of chemistry, and problems associated with the instruction that they are receiving at school or college. As a result, many students will fail to reach their full potential. 1-on-1 chemistry tutoring with an experienced teacher will help them to reach that potential.

“We would like to thank you for helping our son develop proficiency in AP Chemistry, and especially in developing critical thinking skills in this subject. For a sophomore student he has come a long way in understanding complex areas of the subject, and your teaching helped him substantially.”

“I got a 5 on AP chemistry and a 770 on the subject test.
Thank you so much for all your help this year. I couldn’t have done it without you.”

AP Chemistry Crash Course

The best-selling review book that cuts straight to the chase, and delivers higher scores on the AP chemistry exam, is now available in a NEW, 3rd Edition

Updated for the 2020 exam forward, the 3rd Edition of the Crash Course book references the AP Chemistry 9 UNIT organization, and deals with each of the minor changes that were introduced for first examination in 2020.

Not only was this book an awesome resource to use for the AP exam, I have continued to use it as a reference in college. The material is so well organized and so thorough, despite being such a short book. The online review was an awesome bonus and I used it to prepare for the AP exam

Adrian’s Books

Dear Adrian, Today is my birthday. My eighteenth birthday. This feels like a good excuse to write to you – I’ve been meaning to write for a couple years, to thank you for your writing. Eight years ago, aged 10, after forgetting to pack my miniature painting set when I went on holiday, my mum bought me a book to cheer me up. I read your book ‘How to Make a Universe with 92 Ingredients’ at least three times that fortnight, cover-to-cover, and I was hooked by the chemistry, fascinated by the unseen world that I could explore. Inspired by your book, I would steal my brother’s textbooks to read at night, set up the family camera to film my own chemistry videos, and – most importantly – I started experimenting at home. I took my Chemistry GCSE (I live in the UK) aged twelve, four years early. I was the youngest student in the country to get a GCSE A* in 2014 in any subject. Now 18, I’m taking the International Baccalaureate, studying Maths, Chemistry and Physics at higher level. I’m applying to study Natural Sciences (Physical) at Cambridge University. – Tom
