It’s dead easy. Find a tutor, get in touch using our secure website, arrange a lesson, top up your minutes and get started using our very clever online tutoring classroom.
Who it works for
Online tutoring suits anyone studying inside or outside formal education. Our customers include everyone from those at school or univerisity through to home schoolers, overseas students and adult learners.
Your chance to be part of our online masterclasses. The timetable of masterclasses covers all the main topics and revision which we know students look for help with.
Led by academic experts, this is your chance to learn from a leading light without having to leave home.
Unlike video masterclasses, it’s just like being in a lecture hall. You can ask questions, be part of a discussion, and access the notes electronically afterwards. But you can do it all in your pyjamas, without having to leave home. Register your interest and we’ll keep you informed of what’s happening when.
Ask a question
Our free-to-use Q&A hub lets students ask questions of other students and tutors. All you have to do is ask a question and then wait to see what the online community has to say.
An argument is sometimes made that statistics like GDP don’t capture the gains being made by consumers. A television set that used to cost thousands of dollars now costs hundreds of dollars. True. But in other areas, such as finance, education, and health, the opposite has occurred: Expenditures have increased without any obvious gain in outcomes. Much of the financial sector’s growth consists of zero-sum gambling games, with no benefit to the real economy, yet this shows up as a benefit in the GDP. A law degree costs four times what it cost three decades ago, but is not noticeably better, yet this shows as a gain in GDP. Massive high-tech expenditures in medicine (which count as benefits) often yield only modest, zero, or even negative gains in terms of quality or length of life. The net of all these pluses and minuses has yet to be calculated. At this point, there is no basis for assuming a priori that the overcalculations exceed the undercalculations.
---> In this paragraph, I don't understand, what "the overcalculations exceed the undercalculations. " means.
