Help me out, Executive to Professional transition.

1. I cleared my group 1 of executive in December25 and gave group 2 this june attempt. and i am sure i will pass with good aggregate in cmsl and ecipl but can say much about tax its borderline below 50. but for now rather than wasting 2 months wasting for results, Should i opt for professional any single group classes for now and if i don't clear this attempt (which i hope i do) i can always extent my classes?

2. and if yes, then let me know what classes do i look into for professionals i could watch demo and get the lectures? i opted for yes academy in my executive but felt like the faculty waste a lot of time in class. later i bought Shubham sir's lectures which helped me a lot.

3. and what are the other important things i should know regarding this transition from exe to prof. like for now ik that i cant give dec attempt directly after exe i am only eligible to give the june attempt i.e an year after passing exe is it correct? are there any other such things i should make a note of?

do help me out and guide what should i do, if your read everything above or if you are in a similar situation currently.
