Is this Edexcel IAL AS Biology WBI11 trial updated for the 2026 exams?
Yes. The trial lesson and the full course both follow the current Edexcel IAL AS Biology WBI11 specification for the 2026 examinations.
Who teaches the lessons?
Every video, note and worked answer is made by Hosni Showike, Head of Science at Nottingham British School in Kuwait, with more than 21 years of teaching experience, a dual master’s degree in Biochemistry and Biotechnology from the University of Brussels (2003) and an international teaching certificate from the United States. He is the author of eight published textbooks with more than 20,000 copies sold. The recording you watch in this trial is exactly the one paid students see — nothing is cut down for the free version.
What is in the full AS Biology course, and what does it cost?
The IAL AS Biology Complete Course covers Units 1, 2 and 3: recorded lectures, the complete notes library, topic quizzes and the full solved past-paper collections. It is $250. The AS Biology and Chemistry package, which gives you both subjects, is $400. The product page always shows the current price and any offer.
Are solved past papers included in the full course?
Yes. The full course includes the classified and full solved past papers with written answers and video explanations. The worked questions in this trial come from that same collection.
Is this suitable for self-study or homeschooling?
Yes. Every lesson is recorded, so you can work at your own pace, repeat any explanation and revise a topic the night before a test. Parents comparing online tutors can use this free trial to see the teaching before paying for anything.
Who this free Edexcel IAL AS Biology course online trial is for
This is a free trial of the Edexcel IAL AS Biology course online for Unit 1, WBI11. You get one complete lesson video on water and carbohydrates, 16 quiz questions, three trial flipbooks and six worked exam questions — the same recording paid students watch. No sign-up and no card needed, so you can see the teaching before you spend anything.
Who is this for?
This trial is built for students sitting any exam session in the coming two years, and for anyone who wants to see how AS Biology is actually taught before committing. It suits students revising alongside school, students self-studying without a teacher, homeschooling families who need a complete recorded course, and parents comparing online tutors who would rather watch a full lesson than read a sales page. Because every lesson is recorded, you can pause, repeat a difficult explanation and come back to it the night before a test.
How to get the most out of this free lesson
Watch the lesson first without taking notes, then run the quiz cold — the score tells you what actually stuck rather than what felt familiar. After that, open the worked past-paper questions and cover the answer before you read it. Marks in AS Biology are usually lost in the wording, not the science, so comparing your phrasing against a full model answer is the fastest way to gain them.
What the full course includes
- Recorded lectures covering every topic in the specification, taught in the same style as this trial
- The complete notes library, written to be revised from rather than skimmed
- Solved past papers with full written answers and video explanations, classified by topic and available as full papers
- Topic quizzes and flashcards that mark every answer instantly, so you find weak spots before the examiner does
- Access on phone, tablet and laptop — pick up on any device where you left off
For the full unit breakdown, the specification and the notes library, see the AS Biology course page on chem-bio.info. It lists the topics, the exam structure and everything that comes with the paid course, so you can compare it against the free lesson you have just tried.
