Purchased the GSP (Guaranteed Selection Program) specifically for Rajat Udibaba Sir's 10-unit Paper 1 course. After taking the payment, Testbook has restricted access, forcing students into substandard classes by Priti/Anshika instead. Support only provides robotic, copy-pasted excuses about "structure" that were never disclosed before the payment was made. Do not buy GSP. It is a trap to sell you the same basic content at a premium price.
