Welcome to the complete resource for A level Edexcel Biology with Stafford eTuition is a complete resource pack for A Level Edexcel biology. The site is intended to
help students have unlimited 24x7 access to subject content and other resources at their fingertips. The lessons can be accessed online through computers, smart phones or
tablets /ipads/ipods. This document provides a glossary of all the content on the site.
The site contains:
Recorded lectures for all topics for the entire syllabus.
Past paper discussions and model answers.
Tutorials for every topic.
Guidance on How Science Works (HSW)
Guidance on Unit 3 and Unit 6 Practical Papers.
Discussion of pre-release scientific article for Unit 5 paper.
Live teaching sessions (scheduled occasionally)
Consultation and clarification of doubts through the Q & A section of the website http://staffordeducationalservices.com/questions/ , or, via Facebook group – Advanced Level
Edexcel Biology with Stafford https://www.facebook.com/groups/biologywithstafford/
Complete notes for all six units. Available at http://staffordeducationalservices.com/books/ The books cover the entire syllabus for IAL and GCE A level biology and are widely used
globally. The use of simple language and pictorial presentation are the highlights of the
books, making it extremely popular with non-native speakers of English.

GUIDANCE ON eTUITION REGISTRATION, SUBSCRIPTION AND ACTIVATION
Step one: Registration Register for eTuition by going to http://staffordeducationalservices.com/etuition/student-registration/.
After you register, you will be sent an email with your username and password. Login to your eTuition account using this username and password by going to http://staffordeducationalservices.com/etuition/
If you wish to change your eTuition password follow these steps: 1. Log into your account 2. Click on My Profile from the Personal Menu 3. Select Modify My Profile and make the modifications 4. Click on Save
Step two: Installation of software
The eTuition service is run using an online software called eLecta Live. When you first attend a live class on a supported platform this software’s plug- in will be installed automatically through Java. So if you have the latest Java version installed on your computer there is no separate installation file to download.
If Java is not installed then you will be prompted to do so and redirected to Sun Microsystems download site. Follow the instructions on the screen and install the software.
Step three: Activation The site contains a complete archive of lectures, tutorial discussions and past paper discussions, apart from special guidance on How Science
Works and practical skills needed for Edexcel Biology A Level exams and Edexcel International A Level Exams. You will be allowed to access a few recorded sessions in order to test the software. Play these recorded lectures or tutorials to ensure that all
technical issues are sorted out.
Step four: Two day free trial
Email your user name to staffordv@yahoo.com and request for a free trial period of 2 days.
During this period you will have access to view the entire archive of resources to help you decide if you wish to subscribe.
Step five: Subscription The subscription for access to the entire archive of resources is USD 19.90/- per month.
Students in Maldives can pay Mrf. 300/- into Bank of Maldives (contact staffordv@yahoo.com for further details).
International students can pay via Credit card/Debit card or Paypal. http://staffordeducationalservices.com/etuition/recorded-sessions-subscription/
Very important: Once the subscription has been made and the payment has been verified please send me an intimation via email staffordv@yahoo.com about your subscription details and quote your user name. Your account will then be activated.
Step six: Login and get unlimited access to the entire archive of resources for one month.
Use the glossary to help you find a particular topic and search in the archive by using the date alongside each lesson, as it is not possible
to search for lessons (by the name) on the site. The glossary will be update periodically.
Live sessions can also be attended at http://staffordeducationalservices.com/etuition/class-schedule/ Sessions will be scheduled occasionally.
Check this link and attend any scheduled sessions.
