An invitation to join Quatr.us Premium...

Quatr.us subscribers are invited to join Quatr.us Premium service. Quatr.us Premium is a special service for students of any age who want a more personalized experience of the website. With Premium membership, you or your student can email our staff directly with questions and quickly receive personal answers appropriate to your ability and background. You can also request and receive individual consulations, edits, and proof-reading for a paper or project, or help organizing a six-week or year-long history or science curriculum around the Quatr.us website.

Your Quatr.us Premium membership comes with up to five hours a month of instructional time. You can use your hours all at once, in one evening, or spread it out over the the month as an aid in homeschooling or to help with homework. We'll be happy to answer your questions, help with your research, find sources, explain problems, or whatever will help you out the most.

Just email us at karen@quatr.us to get started! Or send us your payment through PayPal: it's the same address, karen@quatr.us. We'll be happy to work with you on a personalized plan, whether by the month or by the year. (If you're under 13, though, we'll need your parent or guardian's permission.) Quatr.us Premium is only $99 a month or $994.00 a year - compare to tutoring programs or online classes.
