How to Purchase Homework Help:

(Step 1) Email homework problems to me, Brad: brawniack@gmail.com

Tips for emailing math problem: Math Typing Tips

PLEASE INCLUDE:
"Homework Help" or "tutoring" in the email subject line.
My deadline -- The latest date & time (central standard time) I can send the work to you.
If you would like...
(a) written out solutions or (b) just the answers or (c) for me to check the homework answers you have already done.
Just homework answers are less expensive than written out homework solutions, but the homework answers may not help you as much as detailed homework solutions.
Your prefered file format -- MS Word, pdf, jpg, etc.
If you would like...
(a) typed homework answers or (b) hand-written homework answers.
Typed homework answers may cost more if there are many equations to be typed.

(Step 2) I will send you a price.
• The price will be $15 to $25 per hour. (Depends on the complexity of the work.)

(Step 3) Send the money by check or money order.
(Step 4) I will complete the requested homework help and email the homework solutions / answers to you as an attached file.

• THIS IS INTENDED AS A STUDY GUIDE AND A WAY FOR YOU TO CHECK YOUR ANSWERS. SIMPLY TURNING IN THESE PROBLEMS FOR A GRADE WILL NOT HELP YOU TO STUDY, AND AS A RESULT, YOUR EXAM SCORES WILL SUFFER AND YOUR GRADE WILL SUFFER. Please do not use this as a way to cheat; cheating will NOT help you in the long run.
