Let's see how much time you need to study for surveying... This is based on the two surveying classes you took and assuming that you remember some of the basic stuff. Of course this is a rough estimate and it will be more (for old geezers like me) or less (possibly for the smart ones like you).
Watch all the CPESR Videos = 12 hours (EET videos will probably be 40+ hours based on my experience with their Seismic, which was over 55 hours. However, the depth that EET videos go into is phenomenal and they assume that your background knowledge is very limited or none).
Work out all the CPESR exercise problems (twice) = 10 hours
Work out all the problems in Reza's workbook (twice) = 40 hours
4 CBTs from CPESR (twice + review of 1/2 hr per try) = 24 hours
Total = 84 hours, say 80 hours for surveying.
Also, you will need about 200 hours for the 8 hour Civil. Thus you will need a total of 280 hours.
With your baby, I will say realistically you will be able to study 12 hours a week. That is assuming 2 hours/6 days a week with one day off for family activities. Do not underestimate the time off that you will need to keep yourself focused and your family happy. Thus, you will need 280/12 = 24 week approximately or about six months. That means you got to start studying right away for the next session. As the exam nears, the last month you probably can squeeze in 16 hours/week where the last 4 hours are added during the weekend. Work out a schedule and see how much you time you can afford. Also, with a baby, you have to think about time required to attend to the baby's needs including regular MD visits etc. Those are the norm with a baby, so you need to work that into your schedule/routine.
Good luck.
