Have questions about our plans & pricing?

Do you offer a plan for schools?

Yes we do. This plan gives every student unlimited access to all videos using a single school login.

What type of payment methods to you accept?

Giancoli Answers accepts Visa, Mastercard, American Express and PayPal. For schools, a PO can be issued and payment is also possible by a physical cheque. Schools should get in touch to make arrangements for this.

How secure is my payment?

All payments are securely processed over HTTPS and your card information never touches the Giancoli Answers server. All payment processing is done by either Stripe or PayPal, both of which are highly respected for their secure practices. Extra technical note: when paying by credit card, the information is submitted using javascript directly from your web browser to Stripe. Stripe then returns a unique token usable only by Giancoli Answer to your browser. Your browser submits this token to the Giancoli Answers server, never the credit card number.

What is the cancellation policy?

Cancelling the monthly plan stops the auto-renewal of the subscription. You still keep access to the solutions until the date to which the plan is paid up. For instance, if you sign up on Sept. 1st, cancel on Sept. 15th, you would still have access until Oct. 1st. Cancellation does not delete your Giancoli Answers account and you can re-subscribe any time. The one year plan does not auto-renew, so cancellation isn't relevant to the one year plan.

What is the refund policy?

Your satisfaction is guaranteed. That's why refunds are always issued upon request. This is possible for payments made within the past 90 days for payments by credit card, or the past 60 days for payments by PayPal. These time limits are due to the payment processors.


do the nodes initially not mean anything then? I thought the nodes would make the resistors not in parallel or series.

Hi saie.joshi,

Thanks for the question. This diagram is a bit tricky since some resistors are in series, whereas others are in parallel. We break it down step by step. If current reaching a node has a choice between multiple paths, then the resistors along the two (or more) paths are in parallel. If current reaching a node has only one option, and that is to proceed through another resistor, then that next resistor is in series. Does that help?

All the best,
Mr. Dychko
