Yes, you can apply for income-based agreements as long as they don’t exceed 30% in aggregate. This means that if your ISA with Microverse is for 15% of your income, then there is another 15% that you could potentially agree to in ISAs beyond your Microverse contract.
While traditional (non-income-based) loans are not counted towards this limit, we strongly recommend that you are careful not to over-extend yourself with loans and ISA agreements.
