Hey Pooja,
Its difficult to face people after so long period, and there mus be atleast a hope of Light in the long night. I had gone through that phase, and thats why i know its very tough, but if u r able to convience her for reappearance, than make her very clear that inspite of preaparing for all subjects with same intensity, try and figure out one subject in each group, in which she can achieve a 65+ score (Accounts in 1st group and Cost Fm in the 2nd grp would be better options) and concentrate higher on those. Because without that it would be a difficult task to achieve the aggregate.
If she would be able to do that, her chances will straight away bounce to double for clearing the group. Best Lucks
