If you are using Foreflight, down load the ACS , part 61 and 91. Then every time you have a question, find the answer, book mark it with a descriptive entry and highlight it. I figured this out late in my training and it helped tremendously for the oral. I also downloaded the AIM, terps, chart supplement, part 97, 8083-2, TAC legend, IFR low legend, NOAA imagery legend, VFR chart legend, Aeronautical chart user's guide and AWC contractions, plus the ifr handbooks. I used them all and it was easier to find answers in those then Sporty's course. Once you find an answer, book mark it, works great.
Many thanks for the suggestions, Paul! I will do that.
