They have two kinds of faculties on board i.e qualified CSP's and academic professionals. They offer all compulsory subjects but not all optional subjects are being offered. Only those optional subjects which are attempted by majority are being offered. It depends upon your selected subjects too that which academy suits you best. You can also go for approach two that is finding separate teachers for each subject in which you need coaching like English etc. Following are the names of few well known and most suggested academies in Islamabad & Lahore.
1- National Officer Academy (NOA) Islamabad
2- KIPS Lahore
2- World Time Academy Lahore

As most of the CSP's are located in these major cities, so other cities do not have that better faculty. You can move to hostel for session and duration will be around 4-4.5 months. Sessions start every month. Kips session is going to start tomorrow in Lahore. Do not know about others. You can search their number online and can contact them for further information.
