Submit Your Problems

The most efficient way of submitting your problems to us is by sending us an e-mail with your problems sent as an attachment. We normally take only a few hours at most to send a quote.

Please make sure to attach your problems to your e-mail in Word, pdf, Excel, or the format of your choice. Please make sure that the files you send are readable and please double check that you are sending all the required materials to solve the problems.

It is especially important that you send all the relevant complementary materials required to solve the problems (for example, a stats problem you send in Word format may call for the use of a Excel document, which you will need to send along).

Lack of the appropriate complementary materials or any missing information that is required to solve the problems may delay unnecessarily the delivery of your solutions.

There are other alternatives, depending on your preferences. Specifically, you may need to send the your problems by fax. In order to do so, please e-mail us to request our fax number.
