Q: I am a senior citizen and I want to work from home. I have basic computer skills and good communication and customer-service skills. I am not trying to get rich, just looking for pocket change. Could you suggest some opportunities that aren't scams? –N.J., Owings Mills, Md.

U.S.: NYSE $20.46 -0.04 -0.20% March 14, 2014 12:37 pm Volume (Delayed 15m) : 136,143 P/E Ratio 37.03 Market Cap $2.07 Billion Dividend Yield 1.17% Rev. per Employee $24,358.3 More quote details and news » Cincinnati; and Alpine Access, Denver, employ or contract with customer-service agents who work from home, handling client calls for retailers, direct-sales vendors and other customers, says Christine Durst, co-founder of RatRaceRebellion.com, a website on home-based work and entrepreneurship.

These jobs typically pay between $8 and $20 per hour and require you to work specific blocks of hours, she says.

However, if you want to make some money but still keep a flexible schedule, other work-at-home options may allow you to set your own hours, says Ms. Durst, co-author of a guidebook on home-based jobs. Website testers provide candid feedback, via video and audio recordings, as they visit various sites. These gigs pay roughly $10 per completed site review and can be found at UserTesting.com and Userlytics.com, she says.

Another possibility: Some sites pay agents to answer questions, usually about 10 cents to 20 cents per query, she says. The questioner usually text-messages the query to one of the sites, and home-based researchers find an answer and send it back. These opportunities can be found at ChaCha.com and KGB.com.

Q:I am applying for a new job, and my prospective employer has asked for my SAT scores. I would like to present myself in the best light and correctly adjust my pre-1995 score. Could you please provide some information on how to do that?


A: Only scores on SAT tests taken before April 1995 need to be adjusted, to make them comparable with today's scores.

A College Board guide to adjusting your scores can be found by doing an Internet search on the words, "SAT Equivalence Tables."

To adjust your old verbal scores, you will in most cases be adding between 10 and 80 points, up to a maximum of 800.

Updates to math scores also vary based on the original score. The biggest point increases, of 30 to 50 points, are assigned to people who scored between 270 and 490 in math on the old test.
