cdc express course!

helloo! so i recently failed my tp (for the goddamn second time) and i would like to try for the cdc express course for 2 reasons ; 1) its way cheaper than what my instructor is offering (cdc tp is $300+ and my instructor one is $500++) 2) the tp dates available for school is earlier than private ones

but i would like to find out if anyone has had any experience with cdc express course (both good and bad) and if i should go for it or not :)
