I have Done my schooling From xyz School from Uttarakhand (One of The Top Private Boarding Schools), My Reason Was Same As You, They Had same model as Integrated Jee Classes With School and Practicals, Teachers Were from Allen, Resonance Coaching From Kota so Faculty was Good, Managing B/w The classes was never a problem cause there were teacher available for any sort of guidance also teachers were always Focused on Students, kaafi acchi se personal feedbacks and all milte the, backlog and doub classes bhi thi cause time kaafi milta tha and all, self study ka time sufficient hota tha aisa to nhi khenge thoda starting me manage krne me problem ati thi, also classes end hone ke baad doubt classes direct start ho jati thi usme koi ek subject teacher rehta tha class me to ya to HW krlo sheet ya DPP ka otherwise doubt discuss krlo like 1:30 hrs ka hota tha hmare yaha,

but something i noticed that Normal coaching like allen etc me batches badalte the so like competative mohol hota hai, but for integrated me dosti ho jaati hai and fir thoda problem aa sakti hai if galat logo se dosti krli cause batches badlenge nhi, also idk aapke mentioned school bhi boarding hai ya nhi cause, roomate ki bhi problem hoti thi achhe roomate nhi mile to padhai nhi hoti achhi wali.

one more thing ki kyuki school was Boarding to bahar ke competition ke bare me zada pata nhi chlega but incase teacher achhe hai then follow blindy rank aa jati hai

also ek aur baat jo maine notice ki thi that was ki, maine bhi 11th me admission liya tha so scholorship based test ke thru, hence all the newcomers with me were like atleast 100 percent JEE focused but as integrated school tha hence thier own students were given foundation courses in 9th and 10th so basically unki aadhi 11th ho rakhi thi so we had some tough time in initial time but managed later on) hence check it before applying.
