Recently I have came across shabbir sir's Geography optional printed class notes (Not handwritten notes) on online site. Are they different from the hand written notes (available everywhere) ? Is it worth buying them? One more question on the same site there is compilation of Shabbir sir's Geography optional test series with explanations for questions of test series as well as of previous years questions please elaborate more on this and also give review.
P.S. - Not promoting anyone.
