A-levels repeat in the 12th entry because I finished the 11 class in 2017 but was thrown out towards the end of 12/1 due to high absenteeism?

I did a high school diploma at a grammar school up to 12/1 grade point average was always about 6-7 pts on the certificates.

My question now that I have successfully completed the 11th grade in high school, can I continue in the 12th grade at another school? But best no night school, since someone knows and had a similar or the same case that one has the 11th Gepackt and, for example, in the 12th Then logged off. Is it possible to enter the 12th class 2 years later?

How is it from home on the laptop to do his abi online since there jmd experiences is that easier than school harder? Does one have the same material as at school? Which subjects are there anyway? Sport is probably gone…

If I understood correctly:

You were at a business high school and you passed the 11th grade and you were placed in the 12th.
In the 12.1 you had too many absences and were thrown out of school.
Now you are looking for ways to catch up with your high school diploma and may want to get back into the 12th.

With the completion of the 11th you have reached a maximum of the secondary school, if you have not had the previously - but no higher degree, which entitles you to enter a 12th grade. Either that is not possible, in some states then only with a college entrance qualification and then only to certain schools.

The only way would be to move to a 12th grade at a business grammar school - and maybe only. (I can't say with certainty, if it is legally possible, because only a request directly at the appropriate Wirtschaftsgymnasium helps.)

Because of "online-Abitur":
There are several commercial, private providers offering to help you with your way to the external high school / foreign examinations. They provide learning material and corrections. They are not recognized schools themselves, they are not allowed to take exams! The exam takes place at a state school.
The drop-out rate is concealed, but should be enormously high.
Then there are no previous grades, but only the exams, which are the same as with all other students in this state. It is not difficult or easier, but the way is certainly the much more strenuous.

An evening school / evening gymnasium is probably out of the question for you anyway. You have to i.d.R. Have completed training or work experience. The same applies to a college ("upper level for adults" in day form).

Otherwise, you are free to apply to various schools that have graduated from high school - then you have to repeat the 11th again.

According to your username you are 20-21 years old. What I know is the age limit at a high school in DE to 21 but I read that. I do not know if that applies in all federal states in DE, because I'm Austrian. All I know is that I still went to school until I was 25, due to miserable circumstances. That was still possible, because I'm an autist. Nevertheless, I did my Matura at the age of 25.

Otherwise, nothing stands in the way that you continue after two years break. If women become pregnant and apply for parental leave, they may also take a break from school or studies. What I read, you have not failed because of 5 and DE 6 (notes). Of course it would be better for you to take another school. If necessary, you take just another state.

Addendum:
In some federal states there's an age limit for entry into a vocational high school. Without education, you may not be more than 19 years old in BW, with education 22. In other states (NRW, I mean) this does not apply.
It depends on the state, what is possible in this regard.

It's about a vocational high school. There are some other age limits, some states have m.W. Also no restrictions.

Addendum 2 - now I was interested. The following applies in Baden-Württemberg:

The entrance examination is based on the requirements of the class or grade in which admission is to take place, whereby the level of knowledge required at the beginning of the respective semester is decisive. The following applies to the implementation: […]

The situation was described quite well by liavah.

Online High School:

Unfortunately, there's still no national German online Abitur and will probably not be there in the foreseeable future, probably for political reasons.
Above all, the German economy needs well-trained skilled workers and no army of full-time graduates.

That it is quite possible, Bavaria proves. There's already something there, but only for people with disabilities, which probably again illustrates the state philosophy in this issue.

I do not think anything will change here if the Greens became the strongest party in Germany and come to power in Berlin with Habeck.

The "Kollegs" already described by liavah, for people with vocational training, are available in NRW partly with partial online instruction, but with at least 2 presence days a week.

As a rule, the correspondence teaching institutes promoting the Abitur, which advertise with yellow-colored full-page advertisements, only send their teaching letters. There, a student is not even ranked higher with an existing Fachhochschulreife.

It would only be necessary to prepare for a school foreign examinations. The necessary information can be paid for. Order at core education. But this is probably not for normal students, but rather for older, willing to educate and strong-willed individualists.
