You need to take tough calls at time to know whether it is worth taking risk or just play it safe. If you feel confident of handling the pressure of writing both groups with ease then you can take it up as a challenge and one of the advantages of writing both groups is the benefit of set off of marks.
On the other hand, if you think you cannot manage all eight papers at one go and wish to do one group at a time, you can opt for this option too. Keep the time factor also in mind when taking decision.
Once, you firm up with your decision, try to stick to it and do not become volatile as it could dent your confidence. Wish you good luck.
