Thanks for your words!
1. Yes, you can add data from your e-log to the OG Tracker. Here is what you should do:
- save all data in the following format for each record: Books-OG12-DT-PS-1-00:03-B-sure-11:43:02|04092012;
1)
Books-OG12 - code for OG12.
2)
DT - id of section (DT - diagnostic test, PS, DS, RC, CR, SC)
3)
PS - question type
4)
1 - question number
5)
00:03 - time in mm:ss format
6)
B - answer {A,B,C,D,E}
7)
sure - sure/guess
8)
11:43:02|04092012 - time|date
Example:
Books-OG13-DT-PS-1-00:03-B-sure-11:43:02|04092012;
Books-OG13-DT-PS-2-00:02-E-sure-11:43:02|04092012;
Books-OG13-DT-PS-3-00:02-A-sure-11:43:02|04092012;
Copy all formatted data into email and send it to your account you can access from your device. Open the email, copy all data and go to GMAT ToolKit > OG Trakcer > export > (from) clipboard.
2. You can use filter to see only questions with a certain tag(s) but you can't set, let's say, "show me 1st, 4th, 15th...". At the same time it would be easy for us to add it in the next update. That's actually a great idea!
Thanks for the questions and one good idea

Best,
Walker
