College Selection and Job issues

I wanted to ask is that I got invitation letter from all the four colleges that I applied for and I just have decided to go on with the two colleges which are my 1st and 3rd option.

The name of the college which I applied are as follows:

1. option
KEMI-TORNIO UAS, SOCIAL SERVICES
Degree Program in Social Services

2. option
Laurea UAS, Espoo Otaniemi
Degree Program in Social Services

3. option
DIACONIA UAS, Järvenpää
Degree Program in Social Services

4. option
Arcada
Degree Program in Human Ageing and Elderly Service

First of all, congratulation for getting Invitation for Entrance from all of the four colleges. Best of Luck for your entrance Examinations. As you told, you have already decided to go forward with two colleges, I think you have analyzed enough to decide the college you have selected.

what should I do next... and i just wanted to know the job opportunity that i can get in these cities. I am also sending u the name of the colleges. Is it ok if I don't appear for the other two colleges I don't want to attain?

You need to set the priority first whether Job is your first priority or just a medium to survive during your studies. The fact is that getting job in entire Finland is really difficult. The capital city Helsinki is bit exception to it but the crowd of people with respect to the less number of opportunities have created a really big challenge to get jobs even in Helsinki. So, all of the towns and cities are similar, there is extremely difficult to get job in Finland. But, once if you are lucky to get the job, the minimal payment from the job will also make you comfortable to survive in Finland. If I need to rank your colleges depending upon the probability of getting job then,
1. Arcada and Laurea Espoo - Since both colleges are in/near by Helsinki.
2. Järvenpää is also near by Helsinki.
3. Kemi is really very smaller town with respect to jobs and opportunities.

Its all depend upon you whether you wanted to attend their entrance or not. It does not matter anything to other colleges if you don't want to attend entrance of another two colleges. But, if these colleges share the entrance score, they will get your entrance score even if you do not attend their entrance.

I also heard that some students even work for 3 months during the vacation and makes enough money to live there during the semester period without working. is it possible??

It is really true, if you get a good job during Summer vacation. But, getting job itself is really much difficult here. So, getting a good job which pays you such a good amount so that you can cover your living expense for a year with the income of only three month; is really much tough job. If you come here with such prediction, you might fail. But, these sentences are not false and if you get really lucky to get a good job, it could be possible. But, being lucky to this extent is really a miracle and happens only with one out of average 2000 students.
