Hello,
Every though every experience counts but it depends on where have you worked, in what capacity, your leadership skills & decision making capacity during your work experience. So, you may look at your past experience & make a strong resume, have a word with few seniors or clients to have their letter of recommendation for your strong application besides writing strong essays. Your applications quality in all would contribute to acceptance in the countries you mentioned.

Hello,
I assume you are enquiring about a Bachelor's degree program. If yes, complete your class 12th with very good grades. More than 75% is recommended. You must also take your IELTS and score at least 7 as required by most universities. UCAS, the common application portal to apply to UK universities is the one you have to check. Follow the timelines mentioned on the UCAS portal and apply on time.

Hello,
Based on the percentile you have and provided here, UK is a better option though not for the highly ranked universities. Canada is way too competitive for your profile. Though a bottom ranked university may accept you chances of a visa are low. Having said that if your profile overall is strong that is excellent SOP and LORs, very good IELTS score and extra-curriculars you may stand a chance.

Dear Deepak,
UK Ph.D stipend varies. Don't expect funding from too many universities, most programs are funded by the students themselves with only 10% to 20% of the fund being provided by the universities. You may expect around GBP1200 to 1800 per month if you have been depending on the university.

Hi Pratap,

Hi,
Actuarial science professionals are in demand in both countries however Australia is a better option in terms of post study work options. If you want to work after studying then UK is not a good option. I will also advice you to check the SOL of the countries to know about the skill shortages.
