How are hard is 35G ALC?

Generally speaking, ALL Army schools are designed to be passable with anyone who meets the pre-requisites.

Theoretically, if one were to be a SFC and reclass, then attend AIT, BLC, ALC, and SLC one right after the other with no "field time" to train, they would be fully capable of passing every school.

(This would never happen because the Army doesn't make you go back and re-take schools - BLC is the same for everyone and ALC and SLC count regardless of reclass. But just as a theoretical example, if it WERE to happen....)'

Even schools like Ranger or SERE, which have remarkably high graduation requirements and attrition rates, CAN be passed (and have been passed) by folks with little to no pertinent training prior to attendance.

Will it be MORE difficult for you than your peers who have been doing the job every day? Sure. But not impossible, or even close. Study when you need to, and don't be afraid to ask your battle buddies for help. In my BNCOC (what ALC used to be), I was teaching the INSTRUCTORS things about system maintenance and troubleshooting, which was one of the core foci for my MOS' BNCOC. I also spent a lot of time helping my peers out, and making sure they understood the system. And one of our requirements was a presentation on an intel system from a sister MOS, I arranged for a study hall in ICE Hall and we did an all-nighter getting everyone's presentation perfect with their timing and slidology.

By helping each other out, every single one of us passed the course with satisfactory marks, with the exception of the course honor grad who exceeded standards.

Let’s start by fixing your account to accurately reflect your rank and full name.

Next, as a 35G, you should have done your job in some way since leaving AIT. The ALC will be as hard as you make it

I haven't because I'm a natty guard and I've gone from orders to orders
