Just to add on to the seniors who are sharing their experiences...you don't have to think much about it.

1. You are not the person who directly printed the papers right? I'm guessing you're just the setter.

2. After discovering missing pg, I'm sure the issue can be resolved (either by you or HOD) just be printing that missing page, and then redistributing it to all the students before the exam ends (exam durations are longer than WAs, more time to rectify).

If the above 2 are somewhat true for your case, there isn't much of a mistake. Usually seen more as an admin lapse or glitch. It could even just be the printer's feeding error that caused it.

If you want my honest opinion? I would rather work with younger GEO3s who are willing to learn while still making mistakes, than some dinosaur GEO5 who doesn't care about anything because he or she has hit the salary ceiling.

So please stay on and keep doing what you're good at
