Hiii, According to me you should not miss your attempt. You should focus on your exams and just make proper strategy w.r.t. each subjects for example if you find studying auditing from Paduka very voluminous then you should refer study material of Surbhi Bansal for quick rivision.
Further just go through the RTPs of at least this term and two earlier terms just for reading purpose.
Then just look at the wiehtage given to each chapters in each subjects according to the questions asked in the respective 6-8 terms in CA exmas and accordingly study the important chapetrs first.
Another important statergy you will have to make is getting complete hold on at least 2 subjects in which you can scor 55 - 60 plus marks and study the 1 which seems hard to you in an average way so that you can manage to score 45 in that subject. By doing this you can find your average comming to 50%.
Another importatnt thing is if you are studing those chapters only which are covering 70% marks then the probability of getting 40 + is on the higher side.
So make your plan according to your strenghth in the subjects.
All the very best to you for your exams and i really hope that you will appear for the exams.
