A differential leveling look started and closed on BM $7,$ elevation $1856\mathrm{.}24$ ft $.$ The plus and minus sight distances were kept approximately equal. Reading $($in feet$)$ listed in the order taken are $4\mathrm{.}52(+S)$ on BM $7,7\mathrm{.}52(-S)$ and $8\mathrm{.}03(+S)$ on TP$1,5\mathrm{.}81(-S)$ and $10\mathrm{.}23(+S)$ on TP$2,6\mathrm{.}89(-S)$ and $5\mathrm{.}43(+S)$ on TP$3,5\mathrm{.}46(-S)$ and $8\mathrm{.}67(+S)$ on TP$4,$ and $10\mathrm{.}98(-S)$ on BM $7.$

$($a$)$ Prepare, check, and adjust the notes. Be sure to perform a page check.

$($b$)$ If this was a simple construction survey, would it meet the allowable misclosure given below of:

$C=0\mathrm{.}02\sqrt[\phantom{2}]{n}in$ feet where $n=$ number $of$ setups

$($c$)$ Using the FGCC Accuracy Standard, what order leveling does this survey represent if the length of the entire circuit loop is $3500$ ft $?$
